From: Jan Glauber <jang@xxxxxxxxxxxxxxxxxx> qdio_cleanup is a wrapper function that should call qdio_shutdown and qdio_free. qdio_free was not called if an error occured in qdio_shutdown resulting in a missing free of allocated resources. Call qdio_free regardless of the return value of qdio_shutdown.
