Subject: [PATCH] ASoC: soc-pcm: Do Digital Mute for both CPU/Codec in same timing.
Git-commit: a9ee331b537a3dfe6778fa4e07c0801f33e474f5
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518

Digital Mute for CPU   is done at soc_pcm_close(), and
Digital Mute for Codec is done at soc_pcm_hw_free().
It is just confusable.
This patch do Digital Mute for both CPU/Codec in same timing.
Then, it cares DAI activity
