From 633ed3df9a65614f14e756424aaff0d317b1b637 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 10 Jun 2015 11:52:00 -0400 Subject: [PATCH] drm/amdgpu: don't enable/disable display twice on suspend/resume MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We were doing it in the common code and in the IP specific code. Remove the IP specific code. The common code handles the ordering properly.
