Subject[PATCH 5.15 054/230] ASoC: rt5682: Re-detect the combo jack after resuming
Date
From: Derek Fang <derek.fang@realtek.com>

[ Upstream commit 2cd9b0ef82d936623d789bb3fbb6fcf52c500367 ]

Sometimes, end-users change the jack type under suspending,
so it needs to re-detect the combo jack type after resuming to
avoid any unexpected behaviors.
