Just one minor comment about docs. I think there are also some remaining references to drm_gem_prime_handle_to_fd() and drm_gem_prime_fd_to_handle() in the drm_prime.c overview. These become stale since this series unexports these functions. With that fixed: Reviewed-by: Simon Ser <contact@xxxxxxxxxxx>
