From 35c3e752f801f375e05688410a65894947a661cc Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 23 Feb 2015 17:45:54 -0500 Subject: [PATCH] drm/radeon: only enable DP audio if the monitor supports it We were enabling DP secondary streams even if the monitor didn't support them. May fix display problems on some DP monitors.
