+From: Hannes Reinecke <hare@suse.de>
+Subject: Fixup return value in scsi_host_lookup()
+References: bnc#468654
+
+scsi_host_lookup should always return an ERR_PTR() value if
+it fails. This has changed in mainline where it returns a
+NULL pointer on failure, but changing it now would be a
+nasty kabi breakage. So stick with the established usage.
