From cae06eb92557f0a073835380e57abee5f8173d73 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 17 Feb 2020 17:28:11 +0900 Subject: [PATCH] ASoC: soc-pcm: use goto and remove multi return When we use some kind of lock, we need to do unlock. In that time, multi unlock/return is not good implementation. This patch add label and use goto at dpcm_fe_dai_open() to reduce such code.
