[Nouveau] [PATCH 0/4] drm/dp_mst: Add DP MST debugfs nodes for all drivers
This is the next version of my patch series for teaching DRM how to automatically create debugfs nodes for drivers with MST topologies. This was originally intended just for nouveau, but has since been expanded to all DRM drivers.

[Nouveau] [PATCH 2/4] drm/dp_mst: Pass entire connector to drm_dp_mst_topology_mgr_init()
There's no actual reason we pass the connector ID instead of a pointer
to the connector itself, and we're going to need the entire connector
(but only temporarily) in order to name MST debugfs folders properly
since connector IDs can't be looked up until the driver has been
registered with userspace which happens after debugfs init.
So, just pass the entire drm_connector struct instead of just it's id.
