Subject: [PATCH 3.12 80/98] xfs: fix two memory leaks in xfs_attr_list.c error paths
From: Mateusz Guzik <mguzik@...hat.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 2e83b79b2d6c78bf1b4aa227938a214dcbddc83f upstream.
This plugs 2 trivial leaks in xfs_attr_shortform_list and
xfs_attr3_leaf_list_int.
