[PATCH 00/17] ASoC: remove cppcheck warnings for multiple SOCs

[Pierre-Louis Bossart]

Trivial cleanups to make cppcheck less verbose.

There should be no functionality change, except for the 'sti_uniperif'
patch where an error check was added.

Pierre-Louis Bossart (17):

[PATCH 15/17] ASoC: ti: omap-mcsp: remove duplicate test

[Pierre-Louis Bossart]

cppcheck warning:

Keeping two separate tests was probably intentional for clarity, but
since this generates warnings we might as well make cppcheck happy so
that we have fewer warnings.

There might be other historical reasons why it ended up like this but
merging them does not make it less cleaner.

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
