Remove lots of superfluous debug messages which just log the function
name. Also, there is no need to announce the various parameters of the
device. This can be discovered via lirc ioctl if needed.

Subject: media: ite-cir: move runtime information into driver data
The carrier, duty cycle etc are not device dependent, and they can be
changed at runtime. By moving them into the allocated struct, we can make
the device specific structures smaller, and we no longer need to copy
the struct.

The in_use variable is set to true when a lirc file is opened, and ir
transmit can only be done by writing to a lirc file descriptor. As a
result when in_use is read, it is always true, so we might as well remove
it.

Subject: media: dvb-usb: Fix memory leak at error in dvb_usb_device_init()
dvb_usb_device_init() allocates a dvb_usb_device object, but it
doesn't release the object by itself even at errors. The object is
released in the callee side (dvb_usb_init()) in some error cases via
dvb_usb_exit() call, but it also missed the object free in other error
paths. And, the caller (it's only dvb_usb_device_init()) doesn't seem
caring the resource management as well, hence those memories are
leaked.
This patch assures releasing the memory at the error path in
dvb_usb_device_init(). Now dvb_usb_init() frees the resources it
allocated but leaves the passed dvb_usb_device object intact. In
turn, the dvb_usb_device object is released in dvb_usb_device_init()
instead.
We could use dvb_usb_exit() function for releasing everything in the
callee (as it was used for some error cases in the original code), but
releasing the passed object in the callee is non-intuitive and
error-prone. So I took this approach (which is more standard in Linus
kernel code) although it ended with a bit more open codes.
Along with the change, the patch makes sure that USB intfdata is reset
and don't return the bogus pointer to the caller of
dvb_usb_device_init() at the error path, too.

Subject: media: dvb-usb: Fix use-after-free access
dvb_usb_device_init() copies the properties to the own data, so that
the callers can release the original properties later (as done in the
commit 299c7007e936 ("media: dw2102: Fix memleak on sequence of
probes")). However, it also stores dev->desc pointer that is a
reference to the original properties data. Since dev->desc is
referred later, it may result in use-after-free, in the worst case,
leading to a kernel Oops as reported.
This patch addresses the problem by allocating and copying the
properties at first, then get the desc from the copied properties.

Subject: media: usbtv: constify static structs
Constify two static structs which are never modified to allow the
compiler to put them in read-only memory.
The only usage of norm_params is only read from it in
usbtv_configure_for_norm(). Making it const shrinks the resulting
ko-file with 300 bytes (tested with gcc 10).
The only usage of usbtv_ioctl_ops is to put its address to the ioctl_ops
field in the video_device struct. Making it const moves ~1kb to
read-only memory.

Subject: media: camss: use v4l2_get_link_freq() to calculate the relevant
clocks
There are places in the camss driver where camss_get_pixel_clock() is
called to get the pixel rate (using V4L2_CID_PIXEL_RATE control) and to
calculate the link frequency from it. There is a case when this would
not work: when V4L2_CID_PIXEL_RATE gets the rate at which the pixels are
read (sampled) from the sensor's pixel array, and this rate is different
from the pixel transmission rate over the CSI link, the link frequency
value can't be calculated from the pixel rate. One needs to use
V4L2_CID_LINK_FREQ to get the link frequency in this case.
Replace such calls to camss_get_pixel_clock() with calls to a wrapper
around v4l2_get_link_freq(). v4l2_get_link_freq() tries V4L2_CID_LINK_FREQ
first, and if it is not implemented by the camera sensor driver, falls
back to V4L2_CID_PIXEL_RATE to calculate the link frequency value from.
Calls to camss_get_pixel_clock() from vfe_[check,set]_clock_rates()
are left intact as it looks like this VFE clock does depend on the
rate the pixel samples comes out of the camera sensor, not on the
frequency at which the link between the sensor and the CSI receiver
operates.

Subject: media: qcom: camss: Fix overflows in clock rate calculations
Because of u32 type being used to store pixel clock rate, expression used
to calculate pipeline clocks (pixel_clock * bpp) produces wrong value due
to integer overflow. This patch changes data type used to store, pass and
retrieve pixel_clock from u32 to u64 to make this mistake less likely to
be repeated in the future.

Subject: media: drivers: media: pci: sta2x11: fix Kconfig dependency on
GPIOLIB
When STA2X11_VIP is enabled, and GPIOLIB is disabled,
Kbuild gives the following warning:
WARNING: unmet direct dependencies detected for VIDEO_ADV7180
Depends on [n]: MEDIA_SUPPORT [=y] && GPIOLIB [=n] && VIDEO_V4L2 [=y] && I2C [=y]
Selected by [y]:
- STA2X11_VIP [=y] && MEDIA_SUPPORT [=y] && MEDIA_PCI_SUPPORT [=y] && MEDIA_CAMERA_SUPPORT [=y] && PCI [=y] && VIDEO_V4L2 [=y] && VIRT_TO_BUS [=y] && I2C [=y] && (STA2X11 [=n] || COMPILE_TEST [=y]) && MEDIA_SUBDRV_AUTOSELECT [=y]
This is because STA2X11_VIP selects VIDEO_ADV7180
without selecting or depending on GPIOLIB,
despite VIDEO_ADV7180 depending on GPIOLIB.

Subject: media: mtk: fix mtk-smi dependency
The mtk-smi driver can now be built as a loadable module, but
this leads to a build time regression when the drivers that
depend on it are built-in:
aarch64-linux-ld: drivers/media/platform/mtk-mdp/mtk_mdp_comp.o: in function `mtk_mdp_comp_clock_on':
mtk_mdp_comp.c:(.text.mtk_mdp_comp_clock_on+0x54): undefined reference to `mtk_smi_larb_get'
aarch64-linux-ld: drivers/media/platform/mtk-mdp/mtk_mdp_comp.o: in function `mtk_mdp_comp_clock_off':
mtk_mdp_comp.c:(.text.mtk_mdp_comp_clock_off+0x12c): undefined reference to `mtk_smi_larb_put'
Add a dependency on the interface, but keep allowing
compile-testing without that driver, as it was originally
intended.

Subject: media: rkisp1: params: remove extra 'if' conditions
There is a repeating code pattern:
if (a || b) {
if (a)
...
if (b)
...
}
In this pattern, the first 'if' is redundant.
The code can be replaced with:
if (a)

syzbot reported memory leak in zr364xx_probe()[1].
The problem was in invalid error handling order.
All error conditions rigth after v4l2_ctrl_handler_init()
must call v4l2_ctrl_handler_free().

Subject: media: cec-notifier: also search for HDMI devices on I2C
Currently the cec_notifier_parse_hdmi_phandle function can only be used
if the HDMI device associated with the CEC device is a platform device.
Extend the function to cover I2C devices as well, as there do exist
some I2C HDMI devices which don't handle CEC internally and need an
external CEC adapter.

Currently the chroma_flags and alpha_flags are being zero'd with a bit-wise

operator rather than an assignment.

Subject: media: saa7134: use sg_dma_len when building pgtable
The new AMD IOMMU DMA implementation concatenates sglist entries under
certain conditions, and because saa7134 accessed the length member
directly, it did not support this scenario.
This fixes IO_PAGE_FAULTs and choppy DMA audio by using the
sg_dma_len macro.

Subject: media: rkisp1: rsz: crash fix when setting src format
When setting the source media bus code in the resizer,
we first check that the current media bus code in the
source is yuv encoded format. This is done by
retrieving the data from the formats list of the isp
entity. This cause a crash when the media bus code on the
source is YUYV8_1_5X8 which is not supported by the isp
entity. Instead we should test the sink format of the resizer
which is guaranteed to be supported by the isp entity.

Subject: media: aspeed: fix clock handling logic
Video engine uses eclk and vclk for its clock sources and its reset
control is coupled with eclk so the current clock enabling sequence works
like below.
Enable eclk
De-assert Video Engine reset
10ms delay
Enable vclk
It introduces improper reset on the Video Engine hardware and eventually
the hardware generates unexpected DMA memory transfers that can corrupt
memory region in random and sporadic patterns. This issue is observed
very rarely on some specific AST2500 SoCs but it causes a critical
kernel panic with making a various shape of signature so it's extremely
hard to debug. Moreover, the issue is observed even when the video
engine is not actively used because udevd turns on the video engine
hardware for a short time to make a query in every boot.
To fix this issue, this commit changes the clock handling logic to make
the reset de-assertion triggered after enabling both eclk and vclk. Also,
it adds clk_unprepare call for a case when probe fails.
clk: ast2600: fix reset settings for eclk and vclk
Video engine reset setting should be coupled with eclk to match it
with the setting for previous Aspeed SoCs which is defined in
clk-aspeed.c since all Aspeed SoCs are sharing a single video engine
driver. Also, reset bit 6 is defined as 'Video Engine' reset in
datasheet so it should be de-asserted when eclk is enabled. This
commit fixes the setting.

Subject: media: i2c: adv7511: remove open coded version of SMBus block read
The open coded version differs from the one in the core in one way: the
buffer will be always copied back, even when the transfer failed. Be
more robust: use the block read from the I2C core and propagate a
potential errno further to the sanity checks.

Subject: media: ngene: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated, GFP_KERNEL can be used because in all cases,
it is called from a probe function and no lock is taken in the between.
The call chain is:
ngene_probe (probe function, used in ngene-cards.c)
--> ngene_get_buffers
--> AllocCommonBuffers (call dma_alloc_coherent)
--> create_ring_buffer (call dma_alloc_coherent)
--> AllocateRingBuffers (call dma_alloc_coherent)

Subject: media: venus: vdec: Add support for display delay and delay enable
controls
Add support for display delay and display delay enable std controls.
With this we implement decoder decode output order (decode vs display).
Once firmware implement few new features the controls will be used
for other use-cases.

'venus_probe()'
If an error occurs after a successful 'of_icc_get()' call, it must be

Use 'devm_of_icc_get()' instead of 'of_icc_get()' to avoid the leak.
Update the remove function accordingly and axe the now unneeded
'icc_put()' calls.

Subject: media: venus: core, venc, vdec: Fix probe dependency error
Commit aaaa93eda64b ("media] media: venus: venc: add video encoder files")
is the last in a series of three commits to add core.c vdec.c and venc.c
adding core, encoder and decoder.
The encoder and decoder check for core drvdata as set and return -EPROBE_DEFER
if it has not been set, however both the encoder and decoder rely on
core.v4l2_dev as valid.
core.v4l2_dev will not be valid until v4l2_device_register() has completed
in core.c's probe().
Normally this is never seen however, Dmitry reported the following
backtrace when compiling drivers and firmware directly into a kernel image.

This patch fixes by
- Only setting drvdata after v4l2_device_register() completes
- Moving v4l2_device_register() so that suspend/reume in core::probe()
stays as-is
- Changes pm_ops->core_function() to take struct venus_core not struct
device
- Minimal rework of v4l2_device_*register in probe/remove

Subject: media: venus: core: Parse firmware-name DT property
On production devices the firmware could be located on different
places, this path could be provided by special firmware-name DT
property.
Here we check for existence of such DT property and if it exist
take the firmware path from there. Otherwise, if the property
is missing we fallback to the predefined path from driver resource
structure.

Since this just makes names too long without any benefit, just drop it.

Subject: media: uapi: move VP8 stateless controls out of staging
Until now, the VP8 V4L2 API was not exported as a public API,
and only defined in a private media header (media/vp8-ctrls.h).
The reason for this was a concern about the API not complete
and ready to support VP8 decoding hardware accelerators.
After reviewing the VP8 specification in detail, and now
that the API is able to support Cedrus and Hantro G1,
we can consider this ready.

Subject: media: vim2m: initialize the media device earlier
Before the video device node is registered, the v4l2_dev.mdev
pointer must be set in order to correctly associate the video
device with the media device. Move the initialization of the
media device up.

Subject: media: ti-vpe: cal: fix subdev mbus_code enumeration
The cal_ctx_v4l2_init_formats() function does not handle error values
correctly when calling enum_mbus_code in subdevs, causing an infinite
loop if the subdev's enum_mbus_code returns some other error than EINVAL.
Fix the error handling.

Subject: media: ti-vpe: cal: Implement media controller centric API
The CAL driver is video node centric, it controls the whole device
through the video device nodes. This limits the possible use cases as it
can't support sources that are more complex than a single subdev. To
support more complex hardware pipelines, implement support for the media
controller centric API. The exposed API can be selected through a module
parameter.

Subject: media: Add parsing for APP14 data segment in jpeg helpers
According to Rec. ITU-T T.872 (06/2012) 6.5.3
APP14 segment is for color encoding, it contains a transform flag, which
may have values of 0, 1 and 2 and are interpreted as follows:
0 - CMYK for images that are encoded with four components
- RGB for images that are encoded with three components
1 - An image encoded with three components using YCbCr colour encoding.
2 - An image encoded with four components using YCCK colour encoding.
This is used in imx-jpeg decoder, to distinguish between
YUV444 and RGB24.

Subject: media: Quit parsing stream if doesn't start with SOI
In the case we get an invalid stream, such as from v4l2-compliance
streaming test, jpeg_next_marker will end up parsing the entire
stream. The standard describes the high level syntax of a jpeg
as starting with SOI, ending with EOI, so return error if the very
first 2 bytes are not SOI.

Subject: media: Avoid parsing quantization and huffman tables
These are optional in struct v4l2_jpeg_header, so skip DHT/DQT segment
parsing if huffman_tables/quantization_tables were not requested by user,
to save time.
However, do count them (num_dht/num_dqt).

Subject: media: imx-jpeg: Add V4L2 driver for i.MX8 JPEG Encoder/Decoder
V4L2 driver for the JPEG encoder/decoder from i.MX8QXP/i.MX8QM application
processors.
The multi-planar buffers API is used.
Baseline and extended sequential jpeg decoding is supported.
Progressive jpeg decoding is not supported by the IP.
Supports encode and decode of various formats:
YUV444, YUV422, YUV420, RGB, ARGB, Gray
YUV420 is the only multi-planar format supported.
Minimum resolution is 64 x 64, maximum 8192 x 8192.
The alignment requirements for the resolution depend on the format,
multiple of 16 resolutions should work for all formats.
v4l2-compliance tests are passing, including the
streaming tests, "v4l2-compliance -s"

Subject: media: media/saa7164: fix saa7164_encoder_register() memory leak bugs
Add a fix for the memory leak bugs that can occur when the
saa7164_encoder_register() function fails.
The function allocates memory without explicitly freeing
it when errors occur.
Add a better error handling that deallocate the unused buffers before the
function exits during a fail.

Subject: media: v4l2-ctrls.c: initialize flags field of p_fwht_params
The V4L2_CID_STATELESS_FWHT_PARAMS compound control was missing a
proper initialization of the flags field, so after loading the vicodec
module for the first time, running v4l2-compliance for the stateless
decoder would fail on this control because the initial control value
was considered invalid by the vicodec driver.
Initializing the flags field to sane values fixes this.

Subject: media: camss: Make ISPIF subdevice optional
This driver supports multiple architecture versions of the Qualcomm ISP.
The CAMSS architecure which this driver is name after, and with the
introduction of this series, the Titan architecture.
The ISPIF is an IP-block that is only present in the CAMSS generation of
the architecture. In order to support the Titan generation, make the
ISPIF an optional subdevice.

From 633b388f85c5c1861793c522b9a1a6db7fd06445 Mon Sep 17 00:00:00 2001

Subject: media: camss: Refactor VFE HW version support
In order to support Qualcomm ISP hardware architectures that diverge
from older architectures, the VFE subdevice driver needs to be refactored
to better abstract the different ISP architectures.
Gen1 represents the CAMSS ISP architecture. The ISP architecture developed
after CAMSS, Titan, will be referred to as Gen2.

Subject: media: camss: Add support for VFE hardware version Titan 170
Add register definitions for version 170 of the Titan architecture
and implement support for the RDI output mode.
The RDI mode as opposed to the PIX output mode for the VFE unit does
not support any ISP functionality. This means essentially only
supporting dumping the output of the whatever the CSI decoder receives
from the sensor.
For example will a sensor outputting YUV pixel format frames, only
allow the VFE to dump those frames as they are received by the ISP
to memory through the RDI interface.

Subject: media: camss: Add missing format identifiers
The CSI-2 spec defines format identifier for Data Type (DT),
and how the Decode Format (DF) & Encode Format (EF) are implemented.
The spec does however not define the DF, EF or Plain Format (PF)
identifiers, as those are vendor specific.
Plain formats describe the size of the pixels written by the RDI
units to memory. PLAIN8 for example has the size 8 bits, and
PLAIN32 32 bits. The appropriate Plain Format is determined by
the Decode Format used. The smallest Plain Format that is able
to contain a pixel of the used Decode Format is the appropriate
one to use.
As the vendor specific identifiers differ between hardware
generations, split them out into separate headers.

From 2f6f8af672038b34d71e16ce9b30c59cc987db2b Mon Sep 17 00:00:00 2001
From: Robert Foss <robert.foss@linaro.org>

Subject: media: camss: Refactor VFE power domain toggling
For Titan ISPs clocks fail to re-enable during vfe_get()
after any vfe has been halted and its corresponding power
domain power has been detached.
Since all of the clocks depend on all of the PDs, per
VFE PD detaching is no option for Gen2 HW.
In order to not have regressions on for Gen1 HW, refactor
the power domain management into hardware version specific
code paths.

Subject: media: cx25821: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'cx25821_riscmem_alloc()' GFP_KERNEL can be
used because either this flag is already used in the call chain, or it is
called from a 'buf_prepare' function.
The call chains are:
vb2_ops.buf_prepare (in cx25821-video.c)
cx25821_buffer_prepare (in cx25821-video.c)
cx25821_risc_buffer
cx25821_riscmem_alloc
snd_cx25821_hw_params (in cx25821-alsa.c) <-- use GFP_KERNEL
cx25821_risc_databuffer_audio
cx25821_riscmem_alloc

Subject: media: dvb_frontend: warn if frontend driver has API issues
the kAPI for a frontend can use 3 different tuning methods:
1. The hardware tracks internally frequency shifts via its
own internal zigzag logic;
2. The hardware has a custom zigzag method, implemented via
fe search() ops;
3. The hardware doesn't have any internal zigzag logic. So,
the Kernel needs to implement it.
Drivers that use the in-kernel software zigzag are required to
provide some parameters for the zigzag code to work. Failing
to do that will just make the Kernel to tune several times
to the very same frequency, delaying the tuning time for
no good reason. This is actually a kAPI violation
(and an uAPI one, as the frequency shift is exported to the
uAPI).
Emit a warning on such case, as the driver needs to be fixed.

Subject: media: dvb-frontends: lgdt3306a.c: remove dead code
Fix the following coccinelle report:
drivers/media/dvb-frontends/lgdt3306a.c:718:5-8:
Unneeded variable: "ret". Return "0" on line 744
Code was enclosed with #if 0 and thus this variable was not needed.
Remove that function altogether.
The lgdt3306a_spectral_inversion function was dropped completely
since the function doesn't do anything. A comment was left at its
calling site to let others know that spectral_inversion defaults
already set for VSB and QAM
Found using - Coccinelle (http://coccinelle.lip6.fr)

Subject: media: mantis: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'mantis_alloc_buffers()' (mantis_dma.c)
GFP_KERNEL can be used because it is called from 'mantis_dma_init()' which
is only called from probe functions and no lock is taken in the between.

Subject: media: mantis: remove orphan mantis_core.c
There is no Makefile rule to have drivers/media/pci/mantis/mantis_core.o
in build since the code overhaul with commit b3b961448f70
("V4L/DVB (13795): [Mantis/Hopper] Code overhaul, add Hopper devices into the PCI ID list").
It looks like drivers/media/pci/mantis/mantis_core.c is a leftover.
Remove the orphan code.

There a 3 array for-loops that don't check the upper bounds of the

full safe.

Subject: media: dvbdev: Fix memory leak in dvb_media_device_free()
dvb_media_device_free() is leaking memory. Free `dvbdev->adapter->conn`
before setting it to NULL, as documented in include/media/media-device.h:
"The media_entity instance itself must be freed explicitly by the driver
if required."

Subject: media: media/siano: Fix transmission parameters reporting for ISDB-T
The currently used functions for converting the transmission mode and guard
interval from the internal values to the DVBv5 API values do not return
correct values for ISDB broadcasts:
- The raw (debugfs) transmission mode is an integer whose values can be
1, 2 or 3, that corresponds to 2K, 4K and 8K FFT modes respectively.
However sms_to_mode() expects values 2, 4 or 8.
- Guard interval, as defined by smscoreapi.h returns "1 divided by value"
instead of 0, 1, 2, and 3 as defined in sms_to_guard_interval_table().
This commit implements ISDB-T specific methods for converting the internal
values for the aforementioned parameters to the DVBv5 API values. It also
adds support for reporting FEC and time interleaving values for each one
of the layers.
[mchehab: fix two coding style whitespace warnings]

Subject: media: cobalt: fix initial EDID
The EDID failed with two edid-decode warnings:
Block 1, CTA-861 Extension Block:
Video Data Block: VIC 16 is the preferred timing, overriding the first detailed timings. Is this intended?
Video Capability Data Block: S_PT is equal to S_IT and S_CE, so should be set to 0 instead.
In addition, the first DTD had a wrong vsync value (6 instead of 5).

Subject: media: em28xx: fix memory leak
If some error occurs, URB buffers should also be freed. If they aren't
freed with the dvb here, the em28xx_dvb_fini call doesn't frees the URB
buffers as dvb is set to NULL. The function in which error occurs should
do all the cleanup for the allocations it had done.
Tested the patch with the reproducer provided by syzbot. This patch
fixes the memleak.

Some devices reference an output terminal as the source of extension
units. This is incorrect, as output terminals only have an input pin,
and thus can't be connected to any entity in the forward direction. The
resulting topology would cause issues when registering the media
controller graph. To avoid this problem, connect the extension unit to
the source of the output terminal instead.
While at it, and while no device has been reported to be affected by
this issue, also handle forward scans where two output terminals would
be connected together, and skip the terminals found through such an
invalid connection.

Subject: media: v4l: fwnode: Rename v4l2_async_register_subdev_sensor_common
Rename v4l2_async_register_subdev_sensor_common as
v4l2_async_register_subdev_sensor. This is a part of the effort to make
the long names present in V4L2 fwnode and async frameworks shorter.

Subject: media: i2c: imx219: Move out locking/unlocking of vflip and hflip
controls from imx219_set_stream
Move out locking/unlocking of vflip and hflip controls from
imx219_set_stream() to the imx219_start_streaming()/
imx219_stop_streaming() respectively.
This fixes an issue in resume callback error path where streaming is
stopped and the controls are left in locked state.

Move incrementing/decrementing runtime PM count to

Subject: media: venus: core: Add io base variables for each block
New silicon means that the pre-determined offsets we have been using
in this driver no longer hold. Existing blocks of registers can exist at
different offsets relative to the IO base address.
This commit adds a routine to assign the IO base hooks a subsequent commit
will convert from absolute to relative addressing.

Subject: media: venus: hfi,pm,firmware: Convert to block relative addressing
An upcoming silicon change places a number of existing blocks within the
Venus at different relative offsets to the base address of IO region.
In order to handle this difference this patch changes the address offsets
of the registers to function as offsets relative to the relevant sub-block
of registers within the IO region not the base address of the IO region.
As a result of this change venus_readl() and venus_writel() are deleted.

Subject: media: venus: hfi: Define block offsets for V6 hardware
This commit defines a range of new base addresses for already defined
blocks.
- CPU_BASE_V6
- CPU_CS_BASE_V6
- CPU_IC_BASE_V6
- WRAPPER_BASE_V6
The base addresses of the blocks are slightly different for 6xx but, aside
from that are layout and bit compatible.
New 6xx specific block addresses will be added in separate commits.

Subject: media: venus: hfi: Add a 6xx boot logic
This patch adds a 6xx specific boot logic. The goal is to share as much
code as possible between 3xx, 4xx and 6xx silicon.
We need to do a different write to WRAPPER_INTR_MASK with an additional
write to CPU_CS_H2XSOFTINTEN_V6 and CPU_CS_X2RPMh_V6.
The other writes are the same for 6xx and non-6xx silicon albeit at
different absolute relative locations to the base of the venus address
space.

Subject: media: venus: hfi, vdec: v6 Add IS_V6() to existing IS_V4() if
locations
In various places in the venus codebase we have if (IS_V4()) which takes
the code down paths for 4xx silicon. This logic is broadly applicable to
6xx silicon also. In this patch we add IS_V6() to various IS_V4() decision
locations.

This patch takes the downstream AXI halt routine and applies it when

Removed poll timeout for LPI register, testing showed the value
would always timeout and work, so the polling did nothing of value.

Subject: media: venus: pm: Toggle 6xx wrapper power in vcodec_control
When in vcodec_control_v4() on the 4xx path we select between one of two
vcodec cores to toggle power control bits. In 6xx there is only one core
which offsets the relevant control registers to a slightly different
address.
This patch accounts for the address offset for 6xx silicon.

Subject: media: venus: hfi: Increase plat_buf_v6 o/p buffer count.
Presently, minimum buffer count for output buffers for h264 &
hevc codec is kept as 8 which might not be sufficient for
few use cases so increasing the value to 18.

Subject: media: v4l2-ctrls.c: fix race condition in hdl->requests list
When a request is re-inited it will release all control handler
objects that are still in the request. It does that by unbinding
and putting all those objects. When the object is unbound the
obj->req pointer is set to NULL, and the object's unbind op is
called. When the object it put the object's release op is called
to free the memory.
For a request object that contains a control handler that means
that v4l2_ctrl_handler_free() is called in the release op.
A control handler used in a request has a pointer to the main
control handler that is created by the driver and contains the
current state of all controls. If the device is unbound (due to
rmmod or a forced unbind), then that main handler is freed, again
by calling v4l2_ctrl_handler_free(), and any outstanding request
objects that refer to that main handler have to be unbound and put
as well.
It does that by this test:
if (!hdl->req_obj.req && !list_empty(&hdl->requests)) {
I.e. the handler has no pointer to a request, so is the main
handler, and one or more request objects refer to this main
handler.
However, this test is wrong since hdl->req_obj.req is actually
NULL when re-initing a request (the object unbind will set req to
NULL), and the only reason this seemingly worked is that the
requests list is typically empty since the request's unbind op
will remove the handler from the requests list.
But if another thread is at the same time adding a new control
to a request, then there is a race condition where one thread
is removing a control handler object from the requests list and
another thread is adding one. The result is that hdl->requests
is no longer empty and the code thinks that a main handler is
being freed instead of a control handler that is part of a request.
There are two bugs here: first the test for hdl->req_obj.req: this
should be hdl->req_obj.ops since only the main control handler will
have a NULL pointer there.
The second is that adding or deleting request objects from the
requests list of the main handler isn't protected by taking the
main handler's lock.

From 7a77379fe1d36b83009a9aee68031e22792c4091 Mon Sep 17 00:00:00 2001
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
Date: Sun, 28 Mar 2021 10:08:19 +0200
Subject: media: cx23885: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'cx23885_risc_buffer()' GFP_KERNEL can be used
because this function is only called from a vb2_ops buf_prepare function.
The call chain is:
cx23885_video_qops.buf_prepare (cx23885-video.c)
--> buffer_prepare (cx23885-video.c)
--> cx23885_risc_buffer
When memory is allocated in 'cx23885_risc_databuffer()' GFP_KERNEL can be
used because this function is only called from a function that already uses
GFP_KERNEL or from a vb2_ops buf_prepare
function.
The call chains are:
snd_cx23885_hw_params (cx23885-alsa.c) --> use GFP_KERNEL
--> cx23885_risc_databuffer
cx23885_qops.buffer_prepare (cx23885-417.c)
or
dvb_qops.buffer_prepare (cx23885-dvb.c)
--> cx23885_buf_prepare
--> cx23885_risc_databuffer
When memory is allocated in 'cx23885_risc_vbibuffer()' GFP_KERNEL can be
used because this function is only called from a vb2_ops buf_prepare
function.
The call chains are:
cx23885_vbi_qops.buffer_prepare (cx23885-vbi.c)
--> cx23885_risc_vbibuffer

Subject: media: tw686x: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'tw686x_audio_dma_alloc()' (tw686x-audio.c)
GFP_KERNEL can be used because it is only called from a probe function
and no spinlock is taken in the between.
The call chain is:
tw686x_probe (tw686x-core.c)
--> tw686x_audio_init (tw686x-audio.c)
--> tw686x_audio_dma_alloc (tw686x-audio.c)
When memory is allocated in 'tw686x_memcpy_dma_alloc()' and in
'tw686x_sg_dma_alloc()' (tw686x-video.c) GFP_KERNEL can be used because
these functions are .alloc functions from a tw686x_dma_ops structure.

The i.MX8 QXP/QM integrated JPEG encoder/decoder is only present on
Freescale/NXP i.MX8 QXP and QM SoCs. Hence add a dependency on
ARCH_MXC, to prevent asking the user about this driver when configuring
a kernel without i.MX8 support.
Drop the "default m" (which means "default y" if CONFIG_MODULES is not
enabled), as merely enabling CONFIG_COMPILE_TEST should not enable
additional code.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

For the adv7604 the hotplug detect pin is controlled through gpio pins from
the SoC, but the adv7611 and adv7612 control the hotplug detect pin
themselves.
But the driver had no support for this, so the HPD was always high, even
when changing the EDID. Add proper support for this to the driver.
Tested with an adv7612.

Subject: media: adv7604: support EDIDs up to 4 blocks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
While the adv7604/11/12 hardware supported EDIDs up to 4 blocks, the
driver didn't. This patch adds support for this. It also improves support
for EDIDs that do not have a Source Physical Address: in that case the
spa location is set to the first byte of the second block, and the
'physical address' is just the two bytes at that location. This is per
the suggestion in the adv76xx documentation for such EDIDs.
Tested with an adv7604 and adv7612.

Subject: media: venus: don't de-reference NULL pointers at IRQ time
Smatch is warning that:
drivers/media/platform/qcom/venus/hfi_venus.c:1100 venus_isr() warn: variable dereferenced before check 'hdev' (see line 1097)
The logic basically does:
hdev = to_hfi_priv(core);
with is translated to:
hdev = core->priv;
If the IRQ code can receive a NULL pointer for hdev, there's
a bug there, as it will first try to de-reference the pointer,
and then check if it is null.
After looking at the code, it seems that this indeed can happen:
Basically, the venus IRQ thread is started with:
devm_request_threaded_irq()
So, it will only be freed after the driver unbinds.
In order to prevent the IRQ code to work with freed data,
the logic at venus_hfi_destroy() sets core->priv to NULL,
which would make the IRQ code to ignore any pending IRQs.
There is, however a race condition, as core->priv is set
to NULL only after being freed. So, we need also to move the
core->priv = NULL to happen earlier.

Subject: media: tc358743: fix possible use-after-free in tc358743_remove()
This driver's remove path calls cancel_delayed_work(). However, that
function does not wait until the work function finishes. This means
that the callback function may still be running after the driver's
remove function has finished, which would result in a use-after-free.
Fix by calling cancel_delayed_work_sync(), which ensures that
the work is properly cancelled, no longer running, and unable
to re-schedule itself.

Subject: media: adv7604: fix possible use-after-free in adv76xx_remove()
This driver's remove path calls cancel_delayed_work(). However, that
function does not wait until the work function finishes. This means
that the callback function may still be running after the driver's
remove function has finished, which would result in a use-after-free.
Fix by calling cancel_delayed_work_sync(), which ensures that
the work is properly cancelled, no longer running, and unable
to re-schedule itself.

Subject: media: dvb-usb: fix memory leak in dvb_usb_adapter_init
syzbot reported memory leak in dvb-usb. The problem was
in invalid error handling in dvb_usb_adapter_init().
for (n = 0; n < d->props.num_adapters; n++) {
....
if ((ret = dvb_usb_adapter_stream_init(adap)) ||
(ret = dvb_usb_adapter_dvb_init(adap, adapter_nrs)) ||
(ret = dvb_usb_adapter_frontend_init(adap))) {
return ret;
}
...
d->num_adapters_initialized++;
...
}
In case of error in dvb_usb_adapter_dvb_init() or
dvb_usb_adapter_dvb_init() d->num_adapters_initialized won't be
incremented, but dvb_usb_adapter_exit() relies on it:
for (n = 0; n < d->num_adapters_initialized; n++)
So, allocated objects won't be freed.

Subject: media: dvb-usb: avoid -Wempty-body warnings
Building with 'make W=1' shows many warnings -Wempty-body warnings like
drivers/media/usb/dvb-usb/vp702x-fe.c: In function 'vp702x_fe_set_frontend':
drivers/media/usb/dvb-usb/vp702x-fe.c:190:46: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
190 | deb_fe("tuning succeeded.\n");
drivers/media/usb/dvb-usb/dtt200u.c: In function 'dtt200u_rc_query':
drivers/media/usb/dvb-usb/dtt200u.c:124:58: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
124 | deb_info("st->data: %*ph\n", 5, st->data);
drivers/media/usb/dvb-usb/m920x.c: In function 'm920x_rc_query':
drivers/media/usb/dvb-usb/m920x.c:207:58: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
207 | deb("Unknown rc key %02x\n", rc_state[1]);
Change the empty dprintk() macros to no_printk(), which avoids this
warning and adds format string checking.

Sparse reports a warning on a cast to u8 of a 16 bits constant.
drivers/media/i2c/rdacm21.c:348:62: warning: cast truncates bits
from constant value (300a becomes a)
Even if the behaviour is intended, silence the sparse warning replacing
the cast with a bitwise & operation.

Subject: media: gscpa/stv06xx: fix memory leak
For two of the supported sensors the stv06xx driver allocates memory which
is stored in sd->sensor_priv. This memory is freed on a disconnect, but if
the probe() fails, then it isn't freed and so this leaks memory.
Add a new probe_error() op that drivers can use to free any allocated
memory in case there was a probe failure.
Thanks to Pavel Skripkin <paskripkin@gmail.com> for discovering the cause
of the memory leak.

The for-loop iterates with a u8 loop counter i and compares this
with the loop upper limit of res->resets_num which is an unsigned
int type. There is a potential infinite loop if res->resets_num
is larger than the u8 loop counter i. Fix this by making the loop
counter the same type as res->resets_num.

Subject: media: v4l2-ctrls: fix reference to freed memory
When controls are used together with the Request API, then for
each request a v4l2_ctrl_handler struct is allocated. This contains
the controls that can be set in a request. If a control is *not* set in
the request, then the value used in the most recent previous request
must be used, or the current value if it is not found in any outstanding
requests.
The framework tried to find such a previous request and it would set
the 'req' pointer in struct v4l2_ctrl_ref to the v4l2_ctrl_ref of the
control in such a previous request. So far, so good. However, when that
previous request was applied to the hardware, returned to userspace, and
then userspace would re-init or free that request, any 'ref' pointer in
still-queued requests would suddenly point to freed memory.
This was not noticed before since the drivers that use this expected
that each request would always have the controls set, so there was
never any need to find a control in older requests. This requirement
was relaxed, and now this bug surfaced.
It was also made worse by changeset
2fae4d6aabc8 ("media: v4l2-ctrls: v4l2_ctrl_request_complete() should always set ref->req")
which increased the chance of this happening.
The use of the 'req' pointer in v4l2_ctrl_ref was very fragile, so
drop this entirely. Instead add a valid_p_req bool to indicate that
p_req contains a valid value for this control. And if it is false,
then just use the current value of the control.
Note that VIDIOC_G_EXT_CTRLS will always return -EACCES when attempting
to get a control from a request until the request is completed. And in
that case, all controls in the request will have the control value set
(i.e. valid_p_req is true). This means that the whole 'find the most
recent previous request containing a control' idea is pointless, and
the code can be simplified considerably.
The v4l2_g_ext_ctrls_common() function was refactored a bit to make
it more understandable. It also avoids updating volatile controls
in a completed request since that was already done when the request
was completed.
