Syzbot reported memory leak in MDIO bus interface, the problem was in
wrong state logic.
MDIOBUS_ALLOCATED indicates 2 states:
1. Bus is only allocated
2. Bus allocated and __mdiobus_register() fails, but
device_register() was called
In case of device_register() has been called we should call put_device()
to correctly free the memory allocated for this device, but mdiobus_free()
calls just kfree(dev) in case of MDIOBUS_ALLOCATED state
To avoid this behaviour we need to set bus->state to MDIOBUS_UNREGISTERED
_before_ calling device_register(), because put_device() should be
called even in case of device_register() failure.

This reverts commit ab609f25d19858513919369ff3d9a63c02cd9e2e.
This patch is correct in the sense that we _should_ call device_put() in
case of device_register() failure, but the problem in this code is more
vast.
We need to set bus->state to UNMDIOBUS_REGISTERED before calling
device_register() to correctly release the device in mdiobus_free().
This patch prevents us from doing it, since in case of device_register()
failure put_device() will be called 2 times and it will cause UAF or
something else.
Also, Reported-by: tag in revered commit was wrong, since syzbot
reported different leak in same function.

The value for maximum number of channels is first calculated based
on the netdev's profile and current function resources (specifically,
number of MSIX vectors, which depends among other things on the number
of online cores in the system).
This value is then used to calculate the netdev's number of rxqs/txqs.
Once created (by alloc_etherdev_mqs), the number of netdev's rxqs/txqs
is constant and we must not exceed it.
To achieve this, keep the maximum number of channels in sync upon any
netdevice re-attach.
Use mlx5e_get_max_num_channels() for calculating the number of netdev's
rxqs/txqs. After netdev is created, use mlx5e_calc_max_nch() (which
coinsiders core device resources, profile, and netdev) to init or
update priv->max_nch.
Before this patch, the value of priv->max_nch might get out of sync,
mistakenly allowing accesses to out-of-bounds objects, which would
crash the system.
Track the number of channels stats structures used in a separate
field, as they are persistent to suspend/resume operations. All the
collected stats of every channel index that ever existed should be
preserved. They are reset only when struct mlx5e_priv is,
in mlx5e_priv_cleanup(), which is part of the profile changing flow.
There is no point anymore in blocking a profile change due to max_nch
mismatch in mlx5e_netdev_change_profile(). Remove the limitation.

Currently in Rx data path IPsec crypto offloaded packets uses
csum_none flag, so checksum is handled by the stack, this naturally
have some performance/cpu utilization impact on such flows. As Nvidia
NIC starting from ConnectX6DX provides checksum complete value out of
the box also for such flows there is no sense in taking csum_none path,
furthermore the stack (xfrm) have the method to handle checksum complete
corrections for such flows i.e. IPsec trailer removal and consequently
checksum value adjustment.
Because of the above and in addition the ConnectX6DX is the first HW
which supports IPsec crypto offload then it is safe to report csum
complete for IPsec offloaded traffic.

Starting with v5.15-rc1, we may now see some am335x beaglebone black
device produce the following error on pruss probe:
Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000
This has started with the enabling of pruss for am335x in the dts files.
Turns out the is caused by the PRM reset handling not waiting for the
reset bit to clear. To fix the issue, let's always wait for the reset
bit to clear, even if there is a separate reset status register.
We attempted to fix a similar issue for dra7 iva with a udelay() in

Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.
So this patch checks hid_device's input is non empty before it's been used.

Syzkaller reported a warning called "rcu detected stall in dummy_timer".
The error seems to be an error in mceusb_dev_recv(). In the case of
-EPROTO error, the routine immediately resubmits the URB. Instead it
should return without resubmitting URB.

Syzbot reported, that mxl111sf_ctrl_msg() uses uninitialized
mutex. The problem was in wrong mutex_init() location.
Previous mutex_init(&state->msg_lock) call was in ->init() function, but
dvb_usbv2_init() has this order of calls:
dvb_usbv2_init()
dvb_usbv2_adapter_init()
dvb_usbv2_adapter_frontend_init()
props->frontend_attach()
props->init()
Since mxl111sf_* devices call mxl111sf_ctrl_msg() in ->frontend_attach()
internally we need to initialize state->msg_lock before
frontend_attach(). To achieve it, ->probe() call added to all mxl111sf_*
devices, which will simply initiaize mutex.

The runtime enabling of the ISPCK (internally clocks the pipeline inside
the ISC) has to be done after the pm_runtime for the ISC dev has been
started.
After the commit by Mauro:
the ISC failed to probe with the error:
atmel-sama5d2-isc f0008000.isc: failed to enable ispck: -13
atmel-sama5d2-isc: probe of f0008000.isc failed with error -13
This is because the enabling of the ispck is done too early in the probe,
and the PM runtime returns invalid request.
Thus, moved this clock enabling after pm_runtime_idle is called.
The ISPCK is required only for sama5d2 type of ISC.
Thus, add a bool inside the isc struct that is platform dependent.
For the sama7g5-isc, the enabling of the ISPCK is wrong and does not make
sense. Removed it from the sama7g5 probe. In sama7g5-isc, there is only
one clock, the MCK, which also clocks the internal pipeline of the ISC.
Adapted the clk_prepare and clk_unprepare to request the runtime PM
for both clocks (MCK and ISPCK) in case of sama5d2-isc, and the single
clock (MCK) in case of sama7g5-isc.

Currently a call to snd_card_new that fails will set card with a NULL
pointer, this causes a null pointer dereference on the error cleanup
path when card it passed to snd_card_free. Fix this by adding a new

new path.

Modify the scaler subdevice to accept setting the resolution of the source
pad (previously the source resolution would always be 3 times the sink for
both dimensions). Now any resolution can be set at src (even smaller ones)
and the sink video will be scaled to match it.
Test example: With the vimc module up (using the default vimc topology)
media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]'
media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]'
media-ctl -d platform:vimc -V '"Scaler":0[fmt:RGB888_1X24/640x480]'
media-ctl -d platform:vimc -V '"Scaler":0[crop:(100,50)/400x150]'
media-ctl -d platform:vimc -V '"Scaler":1[fmt:RGB888_1X24/300x700]'
v4l2-ctl -z platform:vimc -d "RGB/YUV Capture" -v width=300,height=700
v4l2-ctl -z platform:vimc -d "Raw Capture 0" -v pixelformat=BA81
v4l2-ctl --stream-mmap --stream-count=10 -z platform:vimc -d "RGB/YUV Capture" \
--stream-to=test.raw
The result will be a cropped stream that can be checked with the command
ffplay -loglevel warning -v info -f rawvideo -pixel_format rgb24 \

When adding an internal scratch buffer to improve buffer handling when
stopping it was also erroneously used when syncing at capture start.
This led to that the first three buffers captured were always dropped
as they were captured in the scratch buffer instead of in a buffer
provided by the user.
Allow the hardware to be given user provided buffers when preparing for
capture in the stopped state. This still allows the driver to sync with
the hardware and always completes the buffers to user-space in the
correct order as no buffers are completed before the sync is complete.
This change improves the driver as buffers are completed and given to
the user three frames earlier than before.
The change also fixes a warning produced by v4l2-compliance,
warn: v4l2-test-buffers.cpp(448): got sequence number 3, expected 0
