Subject: [PATCH] ASoC: soc-core: add soc_unbind_aux_dev()
Git-commit: 4893a2eb34a9722501915a0b75844aa11956c10d
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

It is easy to read code if it is cleanly using paired function/naming,
like start <-> stop, register <-> unregister, etc, etc.
But, current ALSA SoC code is very random, unbalance, not paired, etc.
It is easy to create bug at the such code, and it will be difficult to
debug.

soc-core.c has soc_bind_aux_dev(), but, there is no its paired
soc_unbind_aux_dev().
This patch adds soc_unbind_aux_dev().
