It's right above the drm_dev_put(). 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(). Aside: This driver gets its devm_ stuff all wrong wrt drm_device and anything hanging off that. Not the only one unfortunately. v2: Explain why this cleanup is possible (Laurent).
