It's right above the drm_dev_put(). This allows us to delete a bit of onion unwinding in udl_modeset_init(). 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).
