From cc1dd5c85cb70ebe09ccf1cc34f29af65442a10f Mon Sep 17 00:00:00 2001 From: David Howells Date: Sun, 12 May 2019 08:05:10 +0100 Subject: [PATCH] afs: Fix incorrect error handling in afs_xattr_get_acl() Fix incorrect error handling in afs_xattr_get_acl() where there appears to be a redundant assignment before return, but in fact the return should be a goto to the error handling at the end of the function.
