Only the V4L2_CID_GAIN and V4L2_CID_EXPOSURE have the volatile flag set. Why can't this code be replaced with case V4L2_CID_GAIN: val = ov5640_get_gain(sensor); if (val < 0) return val; ctrl->val = val; break; > case V4L2_CID_EXPOSURE_AUTO: > - if (ctrl->val == V4L2_EXPOSURE_MANUAL) > - return 0; > val = ov5640_get_exposure(sensor); > if (val < 0) > return val; And same here. -- Regards, Laurent Pinchart
