[PATCH] ASoC: da7219: software reset codec at probe
From: Xing Zheng
Date: Wed Sep 14 2016 - 10:06:28 EST
From: Hsin-Yu Chao <hychao@xxxxxxxxxxxx>
On some platform da7219 codec has persistent power across reboot
so it doesn't reset and cause abnormal jack detection.
Workaround this issue by doing software reset at probe.
