+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: qdio: call qdio_free also if qdio_shutdown fails
+References: bnc#484767,LTC#52207
+
+Symptom:     Warning message after qeth recovery.
+Problem:     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.
+Solution:    Always call qdio_free in qdio_cleanup.
+
