Merge series "ASoC: soc-xxx: 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-xxx.

Kuninori Morimoto (9):
  ASoC: soc-generic-dmaengine-pcm: cleanup cppcheck warning at dmaengine_pcm_hw_params()
  ASoC: soc-generic-dmaengine-pcm: cleanup cppcheck warning at dmaengine_pcm_new()
  ASoC: soc-generic-dmaengine-pcm: cleanup cppcheck warning at dmaengine_copy_user()
  ASoC: soc-dai: cleanup cppcheck warning at snd_soc_dai_link_set_capabilities()
  ASoC: soc-dai: cleanup cppcheck warning at snd_soc_pcm_dai_new()
  ASoC: soc-jack: cleanup cppcheck warning at snd_soc_jack_report()
  ASoC: soc-jack: cleanup cppcheck warning for CONFIG_GPIOLIB
  ASoC: soc-component: cleanup cppcheck warning at snd_soc_pcm_component_pm_runtime_get()
  ASoC: soc-ac97: cleanup cppcheck warning
