Date: Wed, 15 May 2019 17:25:51 +0100 From: David Howells <dhowells@...hat.com> To: linux-afs@...ts.infradead.org Cc: Colin Ian King <colin.king@...onical.com>, Joe Perches <joe@...ches.com>, dhowells@...hat.com, linux-kernel@...r.kernel.org Subject: [PATCH 02/15] 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.
