[alsa-devel] [PATCH 13/16] ASoC: soc-dai: add snd_soc_dai_remove()

[Kuninori Morimoto]

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

Current ALSA SoC is directly using dai->driver->xxx,
thus, it has deep nested bracket, and it makes code unreadable.
This patch adds new snd_soc_dai_remvoe() and use it.
