From f49d45c973984eb805eb989b6220aa7c1ee30bc2 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@amd.com> Date: Tue, 26 Jan 2016 00:30:33 -0500 Subject: drm/amdgpu: don't init fbdev if we don't have any connectors Don't init fbdev if we don't have connectors. E.g., if you have a PX laptop with the displays attached to an IGP with no driver support, you may end up with a blank screen rather than falling back to vesa, etc. Based on a similar radeon patch from Rob Clark.
