From 7edd7a3b61d93b7c5cdf68508966aa48a74fffcb Mon Sep 17 00:00:00 2001 From: Eric Yang Date: Thu, 15 Feb 2018 15:55:31 -0500 Subject: [PATCH 3634/4131] drm/amd/display: fix missing az disable in reset backend Optimization in reset backend skips disable stream if it is already done in dc_stream_set_dpms. However that path does not disable az in order to prevent audio from toggling between internal and external displays. This still need to be done.
