Applied "ASoC: soc-pcm: cleanup soc_pcm_apply_msb()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-pcm: cleanup soc_pcm_apply_msb()

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.

Subject: [PATCH] ASoC: soc-pcm: cleanup soc_pcm_apply_msb()

soc_pcm_apply_msb() apply msb for CPU/Codec,
but, it has duplicate code. The difference is only
SNDRV_PCM_STREAM_PLAYBACK and SNDRV_PCM_STEAM_CAPTURE.

It is very verbose and duplicate code.
This patch simplify code by using snd_soc_dai_get_pcm_stream().
