We can't (at least at the moment) really know here what kind of routings the driver would accept, but we can test a VIDIOC_SUBDEV_G_ROUTING call, followed by a VIDIOC_SUBDEV_S_ROUTING call with the routing we received. Additionally, we can check that the returned pads and flags look fine, and also that setting obviously invalid routing will fail.
