3.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Steve French <[email protected]> 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.
