Merge series "ASoC: soc.h: small cleanups" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

These are small cleanups for soc.h

Kuninori Morimoto (3):
  ASoC: soc.h: add asoc_link_to_cpu/codec/platform() macro
  ASoC: soc.h: fixup return timing for snd_soc_fixup_dai_links_platform_name()
  ASoC: soc.h: return error if multi platform at snd_soc_fixup_dai_links_platform_name()
