There's a bunch of issues with it:

+- Improve late-register debugfs by rolling out the same debugfs pre-register

- 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.
-- The drm_info_list stuff is centered on drm_minor instead of drm_device. For
- anything we want to print drm_device (or maybe drm_file) is the right thing.

- The drm_driver->debugfs_init hooks we have is just an artifact of the old
midlayered load sequence. DRM debugfs should work more like sysfs, where you
can create properties/files for an object anytime you want, and the core
