...all for resources like DP MST topology managers which can potentially be created both before and after the minor device has been registered. So, in order to add driver-wide debugfs files for MST we'll need to be able to handle debugfs initialization for such resources. We do so by introducing drm_debugfs_callback_register() and drm_debugfs_callback_unregister(). These functions allow driver-agnostic parts of DRM to add additional debugfs initialization callbacks at any point during a DRM driver's lifetime.

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. Changes since previous version: - Fix documentation error that got noticed by the kbuild bot in "drm/dp_mst: Pass entire connector to
