PostProcessor::process() is invoked by CameraStream class in case any post-processing is required for the camera stream. The failure or success is checked via the value returned by CameraStream::process(). Now that the post-processor notifies about the post-processing completion operation, we can drop the return value of PostProcessor::process(). The status of post-processing is passed to CameraDevice::streamProcessingComplete() by the PostProcessor::processComplete signal's slot.
