From bb3edbd09287e515fe289fbedbffed5661a0ebda Mon Sep 17 00:00:00 2001 From: Shuming Fan Date: Wed, 19 Oct 2022 17:57:15 +0800 Subject: ASoC: rt1308-sdw: add the default value of some registers [ Upstream commit 75d8b1662ca5c20cf8365575222abaef18ff1f50 ] The driver missed the default value of register 0xc070/0xc360. This patch adds that default value to avoid invalid register access when the device doesn't be enumerated yet.
