Subject: [PATCH] ASoC: Intel: broadwell: Fix oops during module removal
Git-commit: 8382f2949a0def8e9519603b77b3c26f81a66576
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518

When removing the SOF module, the RT286 jack detect
handler will oops if jack detection is not disabled.
Disable the jack in the machine driver remove callback
to prevent this. This fix is only for SOF support and is
not needed for earlier versions.
