3.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpen...@oracle.com>
commit 627aad1c01da6f881e7f98d71fd928ca0c316b1a upstream.
The pciinfo struct has a two byte hole after ->dev_fn so stack
information could be leaked to the user.
This was assigned CVE-2013-2147.
