Merge series "ASoC: soc-component: collect component functions" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
Hi Mark
We have soc-component.c now, but still many component related
functions are implemented many place.
This patch-set collect these into soc-component.c.
v1 -> v2
- remove soc-compress.c exchange
(But I have plan to repost it)
- fixup loop break issue on some functions
- direct return on some functions
