Now that the mode type bit merge logic is fixed to only merge between new probed modes, hopefully we can eliminat the special case for qxl and virtio. That is make the merge the mode type bits from all matching new probed modes, just like every other driver. qxl and virtio got excluded from the merging in commit3fbd6439e4("drm: copy mode type in drm_mode_connector_list_update()") commitabce1ec9b0("Revert "drm: copy mode type in drm_mode_connector_list_update()"") commitb87577b7c7("drm: try harder to avoid regression when merging mode bits") Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Adam Jackson <ajax@redhat.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> [danvet: Resolve conflicts with doc updates.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
