[PATCH v2 09/20] drm: rcar-du: Rely on the default ->best_encoder() behavior

Boris Brezillon
Tue, 07 Jun 2016 11:48:04 -0000

All outputs have a 1:1 relationship between connectors and encoders,
and the driver is relying on the atomic helpers: we can drop the custom
->best_encoder() implementations and let the core call
drm_atomic_helper_best_encoder() for us.
