Brightness and contrast are handled through V4L2 controls. Their configuration bit in the preview engine update attributes table is set to -1 to reflect that. However, the VIDIOC_OMAP3ISP_PRV_CFG ioctl handler doesn't handle -1 correctly as a configuration bit value, and erroneously considers that the parameter has been selected for update by the ioctl caller. Fix this.
