From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Only some of the drm mode object lookups have a corresponding debug
print for the lookup failure. That makes logs a bit hard to parse
when you can't see where the bad object ID is being used. Add a bunch
more debug prints, and unify their appearance.
