From 373225510f9608150a18b3491e756fbf3f58ff24 Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Fri, 27 Mar 2015 20:19:09 +0800 Subject: [PATCH] ASoC: rt5645: Restore HP depop setting in HP off This driver will set RT5645_DEPOP_MAN bit in headphone power up depop process. We need to restore it in headphone power down process. Otherwise, we will get headphone noise when push button function is enabled.
