Tegra is still using the load/unload hooks. That didn't mesh well with
Tomeu's patches (and Tomeu's patches have been thrown out meanwhile
because of that). Still would be neat if tegra could be demidlayered
and loose it's load/unload hooks. See the kerneldoc in drm_drv.c
(especially the DOC: section).
