Merge series "soc-pcm: tidyup snd_pcm_hardware setup for FE/BE" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

These patches tidyup snd_pcm_hardware setup for FE/BE.
[1/5] changes behavior, but I think it is bug-fix.

Kuninori Morimoto (5):
  ASoC: soc-pcm: remove strange format storing
  ASoC: soc-pcm: unpack dpcm_init_runtime_hw()
  ASoC: soc-pcm: add dpcm_runtime_setup_fe()
  ASoC: soc-pcm: add dpcm_runtime_setup()
  ASoC: soc-pcm: unpack dpcm_set_fe_runtime()
