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

Kuninori Morimoto (7):
  ASoC: soc-core: cleanup cppcheck warning at snd_soc_set_dmi_name()
  ASoC: soc-core: cleanup cppcheck warning at snd_soc_get_dai_name()
  ASoC: soc-core: cleanup cppcheck warning at snd_soc_daifmt_parse_format()
  ASoC: soc-core: cleanup cppcheck warning at snd_soc_unregister_component()
  ASoC: soc-core: cleanup cppcheck warning at snd_soc_add_controls()
  ASoC: soc-core: cleanup cppcheck warning at snd_soc_of_parse_audio_simple_widgets()
  ASoC: soc-core: cleanup cppcheck warning at snd_soc_of_parse_audio_routing()
