dss_mgr_wait_for_vsync() uses dssdev->type to find out if the output is going to VENC, HDMI, or something else. This creates a dependency on dssdev, which we want to remove. The task is more logically done by looking at the output to which the overlay manager in question is connected to. This patch changes the code to use output->id to find out which kind of output we use. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Archit Taneja <archit@ti.com>
