Subject[PATCH AUTOSEL 5.0 15/79] ASoC: rt5682: fix jack type detection issue
Date
From: Shuming Fan <shumingf@realtek.com>

[ Upstream commit 675212bfb23394514b7f68ebf3954ba936281ccc ]

The jack type detection needs the main bias power of analog.
The modification makes sure the main bias power on/off while jack plug/unplug.
