[alsa-devel] [PATCH 1/3] ASoC: soc-core: call snd_soc_dapm_shutdown() at soc_cleanup_card_resources()

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

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.

snd_soc_bind_card() is calling snd_soc_dapm_init() for both
card and component.
Let's call paired snd_soc_dapm_shutdown() at paired
soc_cleanup_card_resources().
