From 9c75a9657bdc643e78719ecb139ebff4d5aefe53 Mon Sep 17 00:00:00 2001 From: Derek Fang Date: Tue, 14 Dec 2021 18:50:33 +0800 Subject: [PATCH] ASoC: rt5682: fix the wrong jack type detected commit 8deb34a90f06374fd26f722c2a79e15160f66be7 upstream. 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.
