Subject: [PATCH] ASoC: soc-pcm: remove soc_dpcm_be_digital_mute()
Git-commit: c9645d2a952b7925b6708b24242cd5ed04975648
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518

No one is using soc_dpcm_be_digital_mute().
If it exists only by assumption that "it may be necessary someday",
let's remove it now. Otherwise code maintenance will be difficult.
We can revive it when we really needed it.
Let's remove it, so far.
