We can even delete the drm_driver.release hook now!
This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().
v2: Explain why this cleanup is possible (Laurent).
