[alsa-devel] [PATCH 15/25] ASoC: soc-component: add snd_soc_component_pcm_free()

[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_pcm_free() and use it.
