Merge tag 'drm-intel-fixes-2015-08-14' into drm-intel-next-fixes
Backmerge drm-intel-fixes because a bunch of atomic patch backporting we had to do lead to horrible conflicts. Conflicts: drivers/gpu/drm/drm_crtc.c Just a bit of context conflict between -next and -fixes. drivers/gpu/drm/i915/intel_atomic.c drivers/gpu/drm/i915/intel_display.c Atomic conflicts, always pick the code from -next. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
