We need to cleanup component when soc_probe_component() was failed, or when soc_remove_component() was called. But they are cleanuping component on each way. (And soc_probe_component() doesn't call snd_soc_dapm_free(), but it should). Same code in many places makes code un-understandable.
This patch adds new soc_cleanup_component() and call it from snd_probe_component() and snd_remove_component().
