[3/6] ASoC: soc-core: merge card resources cleanup method

Commit Message

From: Kuninori Morimoto <[e-mail]>

We need to cleanup card resources when snd_soc_instantiate_card() was
failed, or when snd_soc_unbind_card() was called.
But they are cleanuping card resources on each way.
Same code in many places makes code un-understandable.

This patch reuses soc_cleanup_card_resources() for cleanuping code
resource. Then, it makes avoiding cleanup order.
It will be called from snd_soc_instantiate_card() and
snd_soc_unbind_card().

Then, original soc_cleanup_card_resources() included
snd_soc_flush_all_delayed_work(), but it is now separated.
