Merge series "ASoC: cleanup / tidyup soc-pcm/core/component" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

These are not a big deal, but cleanup / tidyup patch for ALSA SoC.

Kuninori Morimoto (5):
  ASoC: soc-pcm: tidyup soc_pcm_hw_clean() - step1
  ASoC: soc-pcm: tidyup soc_pcm_hw_clean() - step2
  ASoC: soc-component: add snd_soc_component_is_codec()
  ASoC: soc-core: tidyup empty function
  ASoC: soc-core: accept zero format at snd_soc_runtime_set_dai_fmt()
