[PATCH AUTOSEL 5.15 09/26] ASoC: rt5682: fix the wrong jack type detected

From: Sasha Levin
Date: Mon Dec 27 2021 - 14:04:22 EST


From: Derek Fang <derek.fang@xxxxxxxxxxx>

[ Upstream commit 8deb34a90f06374fd26f722c2a79e15160f66be7 ]

Some powers were changed during the jack insert detection
and clk's enable/disable in CCF.
If in parallel, the influence has a chance to detect
the wrong jack type, so add a lock.
