I think it's just been left unaddressed until now since there have been even more important things to work on. :-) I'm all for that, btw.; associating bus information to the media device instead of entities was always a little odd (feel free to blame me, too...). Perhaps we could steal some bytes from the union in struct media_entity_desc? :-) -- Cheers, Sakari Ailus sakari.ailus@iki.fi
