Fix a smatch error:
drivers/media/platform/qcom/venus/helpers.c: drivers/media/platform/qcom/venus/helpers.c:678 venus_helper_get_bufreq() error: we previously assumed 'req' could be null (see line 674)
After checking how venus_helper_get_bufreq() is called it is clear that
req is never NULL, so just drop the checks.

This is required to support CS35L41 calibration.
By default, speaker protection firmware will be loaded, if
available. However, different firmware is required to run
the calibration sequence, so it is necessary to add support
to be able to unload, switch and reload firmware.
This patch adds 2 ALSA Controls for each amp:
"DSP1 Firmware Load"
"DSP1 Firmware Type"
"DSP1 Firmware Load" can be used to unload and
load the firmware.
"DSP1 Firmware Type" can be used to switch the
target firmware to be loaded by "DSP1 Firmware Load"
Since loading firmware can add new ALSA controls, it is
necessary to ensure the firmware loading is run asynchronously
from the ALSA control itself to prevent deadlocks.
Note: When switching between firmwares, an ALSA control is
only added if it has not previously existed. If it had existed
previously, it will be re-enabled instead.

The config sequences for running with and without firmware and DSP
are different. The original behavior assumed that we would only
run without DSP only in the case where firmware load failed.
This meant the non-firmware sequence was written with the assumtion
that various registers would be set to their default value.
However, to support the ability to unload the firmware, the
non-firmware register sequence must be updated to update all
required registers, including values that would be defaulted,
in case the firmware sequence, which could have already run,
has changed their value.

stm32-dcmi calls its source subdev with v4l2_subdev_call() using a
v4l2_subdev_state constructed on stack. This means that init_cfg is
never called for that state, and a source subdev that depends on the
init_cfg call may break.
A new macro has been added for this particular purpose, which properly
initializes the state, so let's use v4l2_subdev_call_state_try() here.

Add a helper macro for the situations where a non-MC driver needs to
call a state-operation (operation which takes a subdev state as a
parameter) in try-context in another subdev.
The macro allocates a new subdev state for the called subdev and frees
the state afterwards.
An example use case is a media platform driver testing if a
v4l2_subdev_format would be accepted by a source subdev.
This should not be used in MC drivers.

ASoC: Updates for v5.20
This is a big release thus far and there will probably be more changes
to come, it's a combination of a larger than usual crop of new drivers
and some subsysetm wide cleanups from Charles rather than anything
structural. The SOF and Intel DSP code both also continue to be very
actively developed.
- Restructing of the set_fmt() callbacks to be specified in terms of
the device rather than with semantics depending on if the device is
supposed to be a CODEC or SoC, making things clearer in situations
like CODEC to CODEC links.
- Clean up of the way we flag which DAI naming scheme we use to reflect
the progress that's been made modernising things.
- Merge of more of the Intel AVS driver stack, including some board
integrations.
- New version 4 mechanism for communication with SOF DSPs.
- Suppoort for dynamically selecting the PLL to use at runtime on i.MX
platforms.
- Improvements for CODEC to CODEC support in the generic cards.
- Support for AMD Jadeite and various machines, Intel MetorLake DSPs,
Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP
TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments
TAS2780.

Interrupt context can't sleep. Drivers like Panfrost and MSM are taking
mutex when job is released, and thus, that code can sleep. This results
into "BUG: scheduling while atomic" if locks are contented while job is
freed. There is no good reason for releasing scheduler's jobs in IRQ
context, hence use normal context to fix the trouble.

use the last value of the corresponding enums. This isn't very

This partially reverts commit fd9f8050e355d7fd1e126cd207b06c96cde7f783,
and changes things so that the capability string fields of the encoder
conform to their requirements.
The driver name field should contain the actual driver name, not some
otherwise unused string macro from the driver. To make this clear,
copy the name from the driver's name field.
The card name for the video encoder previously held a static platform
name that was fixed to match MT8173. This obviously doesn't make sense
for newer chips. Since commit fd9f8050e355 ("media: mediatek: vcodec:
Change encoder v4l2 capability value"), this field was changed to hold
the driver's name, or "mtk-vcodec-dec". This doesn't make much sense
either, since this still doesn't reflect what chip this is.
Instead, fill in the card name with "MTxxxx video encoder" with the
proper chip number.
Since commit f2d8b6917f3b ("media: v4l: ioctl: Set bus_info in
v4l_querycap()"), the V4L2 core provides a default value for the
bus_info field for platform and PCI devices. This value will match
the default value for media devices added by commit cef699749f37
("media: mc: Set bus_info in media_device_init()"). These defaults
are stable and device-specific.
Drop the custom capability bus_info from the mtk-vcodec encoder
driver, and use the defaults.
As this patch removes the last usage of MTK_VCODEC_DRV_NAME, remove
the macro as well.

This partially reverts commit a8a7a278c56ad3b4ddd4db9a960e0537d032b0b3,
and changes things so that the capability string fields of the decoder
conform to their requirements.
This recent change caused ChromeOS's decoder to no longer function. This
is due to ChromeOS using the driver name field to match the video device
with its accompanying media device. After the change, they no longer
matched.

Pressing a button on a remote control unit will typically lead to
messages being sent several times per second until the button is released.
Some remote control units indicate long key presses by sending
special "repeat" messages, for which the protocol driver calls
rc_repeat(). Other units repeat the same message over and over,
which will be handled by calling rc_keydown().
The function rc_keydown() never set the LIRC "repeat" flag to distinguish
repeated messages that were sent due to a long keypress, and messages
sent due to repeated short keypresses. While a user-space program may
implement special logic to distinguish long keypresses, it is much simpler
to be able to rely on the flag.
Commit de142c32410649e64d44928505ffad2176a96a9e ("media: lirc: implement
reading scancode") would never set the LIRC_SCANCODE_FLAG_REPEAT flag.
Commit b66218fddfd29f315a103db811152ab0c95fb054
("media: lirc: ensure lirc device receives nec repeats") fixed it up for
rc_repeat() but not rc_keydown().

For camera sensor devices the firmware information of which comes from
non-DT (or some ACPI variants), the kernel makes the information visible
to the drivers in a form similar to DT. This takes place through device's
secondary fwnodes, in which case also the secondary fwnode needs to be
heterogenously (endpoint vs. device) matched.

After moving gfp flags to a separate header, it's possible to move some
cpumask allocators into headers, and avoid creating real functions.

After moving gfp types out of gfp.h, we have to align MAINTAINERS
and Docs, to avoid warnings like this:
>> include/linux/gfp.h:1: warning: 'Page mobility and placement hints' not found
>> include/linux/gfp.h:1: warning: 'Watermark modifiers' not found
>> include/linux/gfp.h:1: warning: 'Reclaim modifiers' not found
>> include/linux/gfp.h:1: warning: 'Useful GFP flag combinations' not found

There's a couple of superfluous inclusions here - remove them before
doing bigger changes.

To avoid circular dependencies, cpumask keeps simple (almost) one-line
wrappers around find_bit() in a c-file.
Commit 47d8c15615c0a2 ("include: move find.h from asm_generic to linux")
moved find.h header out of asm_generic include path, and it helped to fix
many circular dependencies, including some in cpumask.h.
This patch moves those one-liners to header files.

Some cpumask functions have integer return types where return values
are naturally booleans.
