[PATCH v2 00/28] Clean-up ASoC's W=1 build warnings

[PATCH v2 00/28] Clean-up ASoC's W=1 build warnings

[Lee Jones]

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

After these patches are applied, the build system no longer
complains about any W=0 nor W=1 level warnings in sound/soc,
when building for Arm.

Hurrah!

[PATCH v2 03/28] ASoC: fsl: fsl-asoc-card: Use correct format when providing struct documentation

[Lee Jones]

Struct kerneldoc headers need to be prefixed with 'struct $NAME', else
the checker gets confused.

Fixes the following W=1 kernel build warning(s):

 sound/soc/fsl/fsl-asoc-card.c:43: warning: cannot understand function prototype: 'struct codec_priv '

 sound/soc/fsl/fsl-asoc-card.c:104: warning: cannot understand function prototype: 'const struct snd_soc_dapm_route audio_map[] = '

Also the size of the struct does not belong in the description:

[PATCH v2 09/28] ASoC: fsl: fsl_esai: Fix a bunch of kerneldoc issues

[Lee Jones]

Struct headers require a 'struct $NAME' title, all function parameters
require a description and need to be in the format '@.*:', else the
checker gets confused.  Also demote one kerneldoc header where no effort
was made to document any of the function's params.

as it as being unused.  Mark it as __maybe_unused to show that this
behaviour is not only known, it's intentional.
