Merge tag 'v3.10-rc7' into drm-next
Linux 3.10-rc7 The sdvo lvds fix in this -fixes pull commit c3456fb3e4712d0448592af3c5d644c9472cd3c1 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Jun 10 09:47:58 2013 +0200 drm/i915: prefer VBT modes for SVDO-LVDS over EDID has a silent functional conflict with commit 990256aec2f10800595dddf4d1c3441fcd6b2616 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Fri May 31 12:17:07 2013 +0000 drm: Add probed modes in probe order in drm-next. W simply need to add the vbt modes before edid modes, i.e. the other way round than now. Conflicts: drivers/gpu/drm/drm_prime.c drivers/gpu/drm/i915/intel_sdvo.c
