[PATCH 0/5] ALSA: soc: fix sparse warnings

[Takashi Sakamoto]

Hi,

This patchset is to fix some sparse warnings in ALSA SoC part. Below items
are going to be fixed:
 * fix a condition statement with a logical operation
 * purge old way to initialize array
 * missing 'static' qualifier for file local symbols

Although I got many warnings from Intel SST drivers due to confusions of
address spaces (__iomem and __kernel), I still left them as they are,
because they require more codes to fix. I hope Intel developers will
do additional work for them...

[PATCH 1/5] ALSA: soc-da7219: fix inappropriate condition statement

[Takashi Sakamoto]

Sparse reports a below warning.

sound/soc/codecs/da7219.c:804:57: warning: dubious: x & !y

The line includes a condition statement; '(a < b) & !c'. Practically, the
evaluated value of this statement equals to the value of '(a < b) && !c'.
Although, it's not an usual way to use bitwise operations as logical
operations to several conditions.

This commit fixes the bug.

Applied "ASoC: da7219: fix inappropriate condition statement" to the asoc tree

[Mark Brown]

The patch

   ASoC: da7219: fix inappropriate condition statement

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

For your information. I'm happy if you and Intel developers are somewhat 
aware of them.

[PATCH 4/5] ALSA: soc-rt5616: add static qualifier for file local symbols

[Takashi Sakamoto]

Sparse reports below warnings.

rt5616.c:1270:24: warning: symbol 'rt5616_aif_dai_ops' was not declared. Should it be static?
rt5616.c:1277:27: warning: symbol 'rt5616_dai' was not declared. Should it be static?

These two symbols are just used inner the file, thus it's better to add
static qualifier.

This commit adds it.

Applied "ASoC: rt5616: add static qualifier for file local symbols" to the asoc tree

[Mark Brown]

The patch

   ASoC: rt5616: add static qualifier for file local symbols

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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
