The linux-4.1.y specific patch to fix a previous v4.1 UNIT_ATTENTION
read-copy-update conversion regression:
commit 35afa65642a9a88c81913377b93a3a66220f8b9d
Author: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
Date: Wed Sep 23 07:49:26 2015 +0000
target: Fix v4.1 UNIT_ATTENTION se_node_acl->device_list[] NULL pointer
introduced the following compile warning:
drivers/target/target_core_pr.c: In function ‘core_scsi3_pr_seq_non_holder’:
drivers/target/target_core_pr.c:332:3: warning: ‘return’ with no value, in function returning non-void [-Wreturn-type]
Go ahead and fix this up to always returning zero when no ACL
device list exists within core_scsi3_pr_seq_non_holder().
