From 0aa263bba0ed12757fe639248c7c46e6a8d288d5 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Wed, 6 Jan 2016 15:15:37 +0000 Subject: ASoC: wm5110: Fix PGA clear when disabling DRE commit 24338722cfa23fdf4e08c6189a11f7e3a902d86a upstream. We don't want to use a bypassed write in wm5110_clear_pga_volume, we might disable the DRE whilst the CODEC is powered down. A normal regmap_write will always go to the hardware (when not on cache_only) even if the written value matches the cache. As using a normal write will still achieve the desired behaviour of bring the cache and hardware in sync, this patch updates the function to use a normal write, which avoids issues when the CODEC is powered down.
