The simple KMS helpers are deprecated because they only add an intermediate layer between drivers and atomic modesetting. Open-code drm_simple_encoder_init() by calling drm_encoder_init() directly and providing driver-local drm_encoder_funcs. Also check the return value from drm_encoder_init() to avoid silent failures.
