Hi Dave
This series contains several cleanups for the DRM-minor handling. All but the last one reviewed by Daniel and tested by Thierry. Initially, the series included patches to convert minor-handling to a common base-ID, but have been NACKed by Daniel so I dropped them and only included the main part in the last patch. With this in place, drm_global_mutex is no longer needed for minor-handling (but still for device unregistration..). There are some pending patches that try to remove the global mutex entirely, but they need some more reviews and thus are not included.
Thanks David
