Merge series "ASoC: soc-pcm: cleanup cppcheck warning" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

Now I'm posting audio-graph-card2 patch-set, but it seems it needs longer
discussion. Thus I want to post more easy patch first, and reduce my
local patches.

These are cppcheck warning cleanup patches for soc-pcm.

Kuninori Morimoto (5):
  ASoC: soc-pcm: cleanup cppcheck warning at soc_pcm_apply_msb()
  ASoC: soc-pcm: cleanup cppcheck warning at soc_pcm_components_close()
  ASoC: soc-pcm: cleanup cppcheck warning at soc_get_playback_capture()
  ASoC: soc-pcm: cleanup cppcheck warning at dpcm_be_is_active()
  ASoC: soc-pcm: cleanup cppcheck warning at dpcm_runtime_setup_be_chan()
