Subject[PATCH v4 7/7] drm/todo: update the debugfs clean up task
The structs drm_debugfs_info and drm_debugfs_entry introduced a new
debugfs structure to DRM, centered on drm_device instead of drm_minor.
Therefore, remove the tasks related to create a new device-centered
debugfs structure and add a new task to replace the use of
drm_debugfs_create_files() for the use of drm_debugfs_add_file() and

- We probably want to have some support for debugfs files on crtc/connectors and
maybe other kms objects directly in core. There's even drm_print support in
the funcs for these objects to dump kms state, so it's all there. And then the
->show() functions should obviously give you a pointer to the right object.

can create properties/files for an object anytime you want, and the core
