This avoids confusion with the image orientation which is instead expressed by CameraConfiguration::orientation. For this reason, do not compensate the Rotation property when initializing the CameraSensor class but report the value of V4L2_CID_CAMERA_SENSOR_ROTATION or 0 if the control is not available.
