V4L2ControlId and V4L2ControlInfo are just convenience classes to create ControlId and ControlInfo from v4l2_query_ext_control. Therefore, there is no need of being a class. It is used only from V4L2Device. This removes the classes and put the equivalent functions of creating ControlId and ControlInfo in v4l2_device.cpp. Signed-off-by: Hirokazu Honda <hiroh@chromium.org> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
