[alsa-devel] [PATCH 09/16] ASoC: soc-dai: add snd_soc_dai_delay()

[Kuninori Morimoto]

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

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