From: Derek Fang derek.fang@realtek.com
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.
We refer to the below commit of the variant codec (rt5682) to fix this issue. ASoC: rt5682: Fix deadlock on resume
1. Remove rt5682s_headset_detect in rt5682s_jd_check_handler and use jack_detect_work instead of. 2. Use dapm mutex used in CCF to protect most of jack_detect_work.
