From ae2f4849286eed48a3aa79a7b73bb5bcd0c9213b Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Fri, 26 Jul 2019 13:50:01 +0900 Subject: ASoC: soc-component: add snd_soc_component_open() Current ALSA SoC is directly using component->driver->ops->xxx, thus, it is deep nested, and makes code difficult to read, and is not good for encapsulation. This patch adds new snd_soc_component_open() and use it.
