*
- * The V4L2ControlInfo class represents all the information related to a V4L2
- * control, such as its ID, its type, its user-readable name and the expected
- * size of its value data.
- *
- * V4L2ControlInfo instances are created by inspecting the fieldS of a struct
- * v4l2_query_ext_ctrl structure, after it has been filled by the device driver
- * as a consequence of a VIDIOC_QUERY_EXT_CTRL ioctl call.
- *
- * This class does not contain the control value, but only static information on
- * the control, which shall be cached by the caller at initialisation time or
- * the first time the control information is accessed.
+ * The V4L2ControlRange class is a specialisation of the ControlRange for V4L2
+ * controls. It offers a convenience constructor from a struct
+ * v4l2_query_ext_ctrl, and is otherwise equivalent to the ControlRange class.
