sun4i_layer only controls the backend hardware block of the display pipeline. Instead of getting a pointer to the underlying backend through the drm_device structure, leave one in itself. Also drop the drm_device pointer, since it is no longer needed. The next step forward would be to pass the pointer in through sun4i_layers_init as a parameter. This would make it easier to support multiple display pipelines layer on. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
