Subject: [PATCH] ASoC: soc-component: add snd_soc_pcm_component_pcm_free()
Git-commit: 79776da0989733a5bac0a1e635e3a284c3f5c745
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518
Current ALSA SoC is directly using component->driver->xxx,
thus, the code nested deeply, and it makes code difficult to read,
and is not good for encapsulation.
We want to implement component related function at soc-component.c,
but, some of them need to care whole snd_soc_pcm_runtime (= rtd)
connected component.
Let's call component related function which need to care with
for_each_rtdcom() loop as snd_soc_pcm_component_xxx().
This patch adds new snd_soc_pcm_component_pcm_free() and use it.
