From 4beb8e109d30d339d44308a767dd6f5614492f3e Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 22 Jul 2019 10:33:45 +0900 Subject: ASoC: soc-dai: add snd_soc_dai_prepare() 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_prepare() and use it.
