[alsa-devel] [PATCH v2 13/29] ASoC: soc-component: add snd_soc_component_suspend()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

Current ALSA SoC is directly using component->driver->xxx,
thus, it is deep nested, and makes code difficult to read,
and is not good for encapsulation.
This patch adds new snd_soc_component_suspend() and use it.
