drm/repaper: Drop explicit drm_mode_config_cleanup call
Allows us to drop the drm_driver.release callback.
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).
v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)
I also noticed that I've failed to add the error checking,
__must_check caught that.
