+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: zfcp: Fix reference counting for cfdc requests
+References: bnc#487755,LTC#52849
+
+Symptom:     Setting adapter off-line will hang.
+Problem:     The adapter reference count can get negative.
+Solution:    Increase the reference count when issuing
+             cfdc requests.
+
+Acked-by: John Jolly <jjolly@suse.de>
