V4L/DVB (9897): v4l2: Add camera zoom controls
The zoom controls move the zoom lens group to a an absolute position, as a relative displacement or at a given speed until reaching physical device limits. Positive values move the zoom lens group towards the telephoto direction, negative values towards the wide-angle direction.
