[PATCH] ASOC: avs: Fix a sparse warnings for incorrect type in argument

[songxiebing]

The input parameter requirement for snd_pcm_format_physical_with is
snd_pcm_format_t,but params->codec.format is __u32, resulting in a
mismatch error:

sparse warnings: (new ones prefixed by >>)
>> sound/soc/intel/avs/probes.c:147:58: sparse: sparse: incorrect type in argument 1 (different base types) @@     expected restricted snd_pcm_format_t [usertype] format @@     got unsigned int [usertype] format @@

   sound/soc/intel/avs/probes.c:147:58: sparse:     got unsigned int [usertype] format

So here, the format is cast to snd_pcm_format_t.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.1

Thanks!

[1/1] ASoC: intel: avs: Fix type mismatch in variable assignment
      https://git.kernel.org/broonie/sound/c/fd495be8aa19

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

While I see that this just got merged, the signed-off tag shall be the 
last. Other than that, looks good.
