Also remove the now no longer needed build bug on since that's already not needed anymore with drmm_add_final_kfree. Conversion to managed drm_device cleanup is easy, the final drm_dev_put() is already the last thing in both the bind unbind as in the unbind flow. Also, this relies on component.c correctly wrapping bind&unbind in separate devres groups, which it does.
