The current check doesn't handle the case where we don't steal an encoder, but keep it on the current connector. If we repurpose disable_conflicting_encoders to do the checking, we just have to reject the ones that conflict. Changes since v1: - Return early with empty encoder_mask, drm_for_each_connector requires connection_mutex held. Changes since v2: - Add comments for the loops.
