+Subject: ovl: fix random return value on mount
+
+From: Amir Goldstein <amir73il@gmail.com>
+
+commit 8fc646b44385ff0a9853f6590497e43049eeb311 upstream.
+
+On failure to prepare_creds(), mount fails with a random
+return value, as err was last set to an integer cast of
+a valid lower mnt pointer or set to 0 if inodes index feature
+is enabled.
+
