The documentation for struct drm_minor already states this, but that's not always that easy to find. Also due to historical reasons we still have the minor-centric (like drm_debugfs_create_files), but since this is now getting fixed we can put a few more pointers in place as to how this should be done ideally. Motvated by some discussion with Rodrigo on irc about how drm/xe should lay out its sysfs interfaces.
