3.5.7.26 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Dan Carpenter <dan.carpen...@oracle.com>
commit 8d1e72250c847fa96498ec029891de4dc638a5ba upstream.
The DevInfo.u32Reserved[] array isn't initialized so it leaks kernel
information to user space.
