 Some of these date from the very introduction of KMS in 2008 ...
 
-- drm_mode_config.crtc_idr is misnamed, since it contains all KMS object. Should
-  be renamed to drm_mode_config.object_idr.
-
 - drm_display_mode doesn't need to be derived from drm_mode_object. That's
   leftovers from older (never merged into upstream) KMS designs where modes
   where set using their ID, including support to add/remove modes.
