From 799d37815f470739ed079e2fea49077decaee3d3 Mon Sep 17 00:00:00 2001
From: Gary Ching-Pang Lin <glin@suse.com>
Date: Wed, 2 Jan 2013 17:09:35 +0800
Subject: [PATCH 7/7] Initialize the variable to prevent a potential crash
In issue_mok_request(), old_req.Data must be intialized before
"goto error", or the process would segfault when freeing old_req.Data.
