Subject: [PATCH] ASoC: soc-core: use snd_soc_lookup_component() at snd_soc_unregister_component()
Git-commit: ac6a4dd3e9f09697ab6a1774d7ab6a34e7ab36fa
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518

snd_soc_unregister_component() is now finding component manually,
but we already have snd_soc_lookup_component() to find component;
Let's use existing function.
