MODULE_SUPPORTED_DEVICE was added in pre-git era and never was
implemented. We can safely remove it, because the kernel has grown
to have many more reliable mechanisms to determine if device is
supported or not.

strlcpy is deprecated. see: Documentation/process/deprecated.rst
Change the calls that do not use the strlcpy return value to the
preferred strscpy.
Done with cocci script:
@@
expression e1, e2, e3;
@@
- strlcpy(
+ strscpy(
e1, e2, e3);
This cocci script leaves the instances where the return value is
used unchanged.
After this patch, sound/ has 3 uses of strlcpy() that need to be
manually inspected for conversion and changed one day.
$ git grep -w strlcpy sound/
sound/usb/card.c: len = strlcpy(card->longname, s, sizeof(card->longname));
sound/usb/mixer.c: return strlcpy(buf, p->name, buflen);
sound/usb/mixer.c: return strlcpy(buf, p->names[index], buflen);
Miscellenea:
o Remove trailing whitespace in conversion of sound/core/hwdep.c

Pull sound fixes from Takashi Iwai:
"A collection of small fixes over several drivers, but all are driver-
specific and nothing looks scary.
Slightly large changes are seen in ASoC qcom driver for the bugs that
were revealed by the recent ASoC core change to report the invalid
register access errors. Also ASoC fsl got a slight intensive change
for the distortion fix.
Others are only trivial fixes or device-specific quirks"

"This became wide and scattered updates all over the sound tree as
diffstat shows: lots of (still ongoing) refactoring works in ASoC,
fixes and cleanups caught by static analysis, inclusive term
conversions as well as lots of new drivers. Below are highlights:
ASoC core:
- API cleanups and conversions to the unified mute_stream() call

- Use helper macros to retrieve RTD from substreams
ASoC drivers:
- Lots of fixes and cleanups in Intel ASoC drivers
- Lots of new stuff: Freescale MQS and i.MX6sx, Intel KeemBay I2S,
Maxim MAX98360A and MAX98373 SoundWire, various Mediatek boards,
nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries
boards, TI J721e EVM
ALSA core:
- Minor code refacotring for SG-buffer handling
HD-audio:
- Generalization of mute-LED handling with LED classdev
- Intel silent stream support for HDMI
- Device-specific fixes: CA0132, Loongson-3

These are all harmless here as only the low 8 bit are passed down
anyway. Change the macros to inline functions to make the code
more readable and also avoid the warning.
Strictly speaking those functions also need locking to make the
read/write pair atomic, but it seems unlikely that anyone would
still run into that issue.

Pull sound updates from Takashi Iwai:
"As the diffstat shows we've had again a lot of works done for this
cycle: the majority of changes are the continued componentization and
code refactoring in ASoC, the tree-wide PCM API updates and cleanups
and SOF updates while a few ASoC driver updates are seen, too.
Here we go, some highlights:
Core:
- Finally y2038 support landed to ALSA ABI; some ioctls have been
extended and lots of tricks were applied
- Applying the new managed PCM buffer API to all drivers; the API
itself was already merged in 5.5
- The already deprecated dimension support in ALSA control API is
dropped completely now
- Verification of ALSA control elements to catch API misuses
ASoC:
- Further code refactorings and moving things to the component level
- Lots of updates and improvements on SOF / Intel drivers; now
including common HDMI driver and SoundWire support
- New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
RT1015 and RT1308
HD-audio:
- Improved ring-buffer communications using waitqueue
- Drop the superfluous buffer preallocation on x86
Others:
- Many code cleanups, mostly constifications over the whole tree
- USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
- FireWire: code refactoring for oxfw and dice drivers"
