From 8382f2949a0def8e9519603b77b3c26f81a66576 Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Mon, 27 Apr 2020 09:29:53 -0700 Subject: [PATCH] ASoC: Intel: broadwell: Fix oops during module removal 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.
