3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steve French <smfre...@gmail.com>
commit 18f39e7be0121317550d03e267e3ebd4dbfbb3ce upstream.
As Raphael Geissert pointed out, tcon_error_exit can dereference tcon
and there is one path in which tcon can be null.
