Some drivers call video_set_flush_dcache() to indicate that they want to have the dcache flushed for the frame buffer. These drivers benefit from our new video damage control, because we can reduce the amount of memory that gets flushed significantly. This patch enables video damage control for all device drivers that call video_set_flush_dcache() to make sure they benefit from it.
