Subject: [PATCH 5.3 018/140] ASoC: intel: sof_rt5682: add remove function to disable jack

From: Jaska Uimonen <jaska.uimonen@...el.com>

[ Upstream commit 6ba5041c23c1062d4e8287b2b76a1181538c6df1 ]

When removing sof module the rt5682 jack handler will oops
if jack detection is not disabled. So add remove function,
which disables the jack detection.
