  Running sparse on fsl_qmc_audio (make C=1) raises the following warnings:
 fsl_qmc_audio.c:387:26: warning: restricted snd_pcm_format_t degrades to integer
 fsl_qmc_audio.c:389:59: warning: incorrect type in argument 1 (different base types)
 fsl_qmc_audio.c:389:59:    expected restricted snd_pcm_format_t [usertype] format
 fsl_qmc_audio.c:389:59:    got unsigned int [assigned] i

 fsl_qmc_audio.c:573:62:    got int [assigned] i

These warnings are due to snd_pcm_format_t values handling done in the
driver. Some macros and functions exist to handle safely these values.

Use dedicated macros and functions to remove these warnings.

Applied to

Thanks!

[1/1] ASoC: fsl: fsl_qmc_audio: Fix snd_pcm_format_t values handling
      commit: 5befe22b3eebd07b334b2917f6d14ce7ee4c8404

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
