When user is requesting for DSP capability, the process pd type is
getting updated to USER_PD which is incorrect as DSP will assume the
process which is making the request is a user PD and this will never
get updated back to the original value. The actual PD type should not
be updated for capability request and it should be serviced by the
respective PD on DSP side. Don't change process's PD type for DSP
capability request.

User is passing capability ioctl structure(argp) to get DSP
capabilities. This argp is copied to a local structure to get domain
and attribute_id information. After getting the capability, only
capability value is getting copied to user argp which will not be
useful if the use is trying to get the capability by checking the
capability member of fastrpc_ioctl_capability structure. Copy the
complete capability structure so that user can get the capability
value from the expected member of the structure.

The DSP capability request call expects 2 arguments. First is the
information about the total number of attributes to be copied from
DSP and second is the information about the buffer where the DSP
needs to copy the information. The current design is passing the
information about the size to be copied from DSP which would be
considered as a bad argument to the call by DSP causing a failure
suggesting the same. The second argument carries the information
about the buffer where the DSP needs to copy the capability
information and the size to be copied. As the first entry of
capability attribute is getting skipped, same should also be
considered while sending the information to DSP. Add changes to
pass proper arguments to DSP.

If a process is killed while writing to a /dev/ttymxc* device in RS485
mode, we observe that the RTS signal is left high, thus making it
impossible for other devices to transmit anything.
Moreover, the ->tx_state variable is left in state SEND, which means
that when one next opens the device and configures baud rate etc., the
initialization code in imx_uart_set_termios dutifully ensures the RTS
pin is pulled down, but since ->tx_state is already SEND, the logic in
imx_uart_start_tx() does not in fact pull the pin high before
transmitting, so nothing actually gets on the wire on the other side
of the transceiver. Only when that transmission is allowed to complete
is the state machine then back in a consistent state.
This is completely reproducible by doing something as simple as
seq 10000 > /dev/ttymxc0
and hitting ctrl-C, and watching with a logic analyzer.

Errata i2310[0] says, Erroneous timeout can be triggered,
if this Erroneous interrupt is not cleared then it may leads
to storm of interrupts.
Commit 9d141c1e6157 ("serial: 8250_omap: Implementation of Errata i2310")
which added the workaround but missed ensuring RX FIFO is really empty
before applying the errata workaround as recommended in the errata text.
Fix this by adding back check for UART_OMAP_RX_LVL to be 0 for

iwl_mvm_get_bss_vif might return a NULL or ERR_PTR. Some of the callers
check only the NULL case, and some doesn't check at all.
Some of the callers even have a pointer to the mvmvif of the bss vif,
so we don't even need to call this function, and can simply get the vif
from mvmvif. Do it for those cases, and for the others - properly check
if IS_ERR_OR_NULL

descriptor
Syzbot has identified a bug in usbcore (see the Closes: tag below)
caused by our assumption that the reserved bits in an endpoint
descriptor's bEndpointAddress field will always be 0. As a result of
the bug, the endpoint_is_duplicate() routine in config.c (and possibly
other routines as well) may believe that two descriptors are for
distinct endpoints, even though they have the same direction and
endpoint number. This can lead to confusion, including the bug
identified by syzbot (two descriptors with matching endpoint numbers
and directions, where one was interrupt and the other was bulk).
To fix the bug, we will clear the reserved bits in bEndpointAddress
when we parse the descriptor. (Note that both the USB-2.0 and USB-3.1
specs say these bits are "Reserved, reset to zero".) This requires us
to make a copy of the descriptor earlier in usb_parse_endpoint() and
use the copy instead of the original when checking for duplicates.

Usb device connect may not be detected after runtime resume if
xHC is reset during resume.
In runtime resume cases xhci_resume() will only resume roothubs if there
are pending port events. If the xHC host is reset during runtime resume
due to a Save/Restore Error (SRE) then these pending port events won't be
detected as PORTSC change bits are not immediately set by host after reset.
Unconditionally resume roothubs if xHC is reset during resume to ensure
device connections are detected.
Also return early with error code if starting xHC fails after reset.
Issue was debugged and a similar solution suggested by Remi Pommarel.
Using this instead as it simplifies future refactoring.

ath11k and ath12k devices to work with a new power sequencing
subsystem.
Major changes:

* DebugFS support for datapath statistics
* WCN7850: support for WoW (Wake on WLAN)
* WCN7850: device-tree bindings
ath11k
* QCA6390: device-tree bindings

[Why]
During resume, observe that we receive CSN event before we start topology
probing. Handling CSN at this moment based on uncertain topology is
unnecessary.
[How]
Add checking condition in drm_dp_mst_handle_up_req() to skip handling CSN
if the topology is yet to be probed.

With commit a81dbd0463ec ("serial: imx: set receiver level before

caused a regression when using SDMA, where the receiver level is 9
instead of 8 (default). This change will first check if the receiver
level is zero and only then set it to the default. This still avoids the
interrupt storm when the receiver level is zero.

Commit 205c50306acf ("wifi: wilc1000: fix RCU usage in connect path")
made sure that the IEs data was manipulated under the relevant RCU section.
Unfortunately, while doing so, the commit brought a faulty implicit cast
from int to u8 on the ies_len variable, making the parsing fail to be
performed correctly if the IEs block is larger than 255 bytes. This failure
can be observed with Access Points appending a lot of IEs TLVs in their
beacon frames (reproduced with a Pixel phone acting as an Access Point,
which brough 273 bytes of IE data in my testing environment).
Fix IEs parsing by removing this undesired implicit cast.

For SDX72 MBIM mode, it starts data mux id from 112 instead of 0.
This would lead to device can't ping outside successfully.
Also MBIM side would report "bad packet session (112)". In order
to fix this issue, we decide to use the device name of MHI
controller to do a match in wwan side. Then wwan driver could
set a corresponding mux_id value according to the MHI product.

MHI devices usually have a product/device name to identify each device
uniquely. So let's specify that name in 'struct mhi_controller' so that the
client drivers can use this name to uniquely identify the devices and apply
any device specific quirks.

bgpio_bits must be aligned with the data bus width. For example, on a
32 bit big endian system and we only have 16 GPIOs. If we only assume
bgpio_bits=16 we can never control the GPIO because the base address
is the lowest address.

Panfrost DRM driver uses devfreq to perform DVFS, while using simple_ondemand
devfreq governor by default. This causes driver initialization to fail on
boot when simple_ondemand governor isn't built into the kernel statically,
as a result of the missing module dependency and, consequently, the required
governor module not being included in the initial ramdisk. Thus, let's mark
simple_ondemand governor as a softdep for Panfrost, to have its kernel module
included in the initial ramdisk.
This is a rather longstanding issue that has forced distributions to build
devfreq governors statically into their kernels, [1][2] or has forced users
to introduce some unnecessary workarounds. [3]
For future reference, not having support for the simple_ondemand governor in
the initial ramdisk produces errors in the kernel log similar to these below,
which were taken from a Pine64 RockPro64:
panfrost ff9a0000.gpu: [drm:panfrost_devfreq_init [panfrost]] *ERROR* Couldn't initialize GPU devfreq
panfrost ff9a0000.gpu: Fatal error during GPU init
panfrost: probe of ff9a0000.gpu failed with error -22
Having simple_ondemand marked as a softdep for Panfrost may not resolve this
issue for all Linux distributions. In particular, it will remain unresolved
for the distributions whose utilities for the initial ramdisk generation do
not handle the available softdep information [4] properly yet. However, some
Linux distributions already handle softdeps properly while generating their
initial ramdisks, [5] and this is a prerequisite step in the right direction
for the distributions that don't handle them properly yet.

In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *. This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.
Because the match() callback is in all busses, all busses are modified
to handle this properly. This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.
For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

The arm64 asm/arm_pmuv3.h depends on defines from
linux/perf/arm_pmuv3.h. Rather than depend on include order, follow the
usual pattern of "linux" headers including "asm" headers of the same
name.
With this change, the include of linux/kvm_host.h is problematic due to
circular includes:
In file included from ../arch/arm64/include/asm/arm_pmuv3.h:9,
from ../include/linux/perf/arm_pmuv3.h:312,
from ../include/kvm/arm_pmu.h:11,
from ../arch/arm64/include/asm/kvm_host.h:38,
from ../arch/arm64/mm/init.c:41:
../include/linux/kvm_host.h:383:30: error: field 'arch' has incomplete type
Switching to asm/kvm_host.h solves the issue.

There are no non-DT based PMU users for v6 or v7, so drop the custom
non-DT probe table. Unfortunately XScale still needs non-DT probing.
Note that this drops support for arm1156 PMU, but there are no arm1156
based systems supported in the kernel.

The IS_ENABLED(CONFIG_ARM64) check for threshold support is unnecessary.
The purpose is to not enable thresholds on arm32, but if threshold is
non-zero, the check against threshold_max() just above here will have
errored out because threshold_max() is always 0 on arm32.

If the user has requested a counting threshold for the CPU cycles event,
then the fixed cycle counter can't be assigned as it lacks threshold
support. Currently, the thresholds will work or not randomly depending
on which counter the event is assigned.
While using thresholds for CPU cycles doesn't make much sense, it can be
useful for testing purposes.
