[PATCH] ASoC: rsnd: mark PM functions __maybe_unused

[PATCH] ASoC: rsnd: mark PM functions __maybe_unused

[Arnd Bergmann]

The suspend/resume callbacks are now optional, leading to a warning
when they are unused:

sound/soc/sh/rcar/core.c:1548:12: error: 'rsnd_resume' defined but not used [-Werror=unused-function]
 static int rsnd_resume(struct device *dev)
            ^~~~~~~~~~~
sound/soc/sh/rcar/core.c:1539:12: error: 'rsnd_suspend' defined but not used [-Werror=unused-function]
 static int rsnd_suspend(struct device *dev)

This marks the as __maybe_unused to avoid the warning.

[Mark Brown]

The patch

   ASoC: rsnd: mark PM functions __maybe_unused

has been applied to the asoc tree at

   https://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
