Subject: [PATCH] ASoC: soc-ops: use snd_soc_card_get_kcontrol() at snd_soc_limit_volume()
Git-commit: 0881ab6e74b0be7df3da3abdf7caeb2552f907d2
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518

snd_soc_limit_volume() is finding snd_kcontrol by using original coding,
but we already have snd_soc_card_get_kcontrol().
Let's use existing function.
