From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
[ Upstream commit 7df566bbdd0af0785542b89466a937e94257fcfb ]
This function is called from dcbnl_build_peer_app(). The "info"
struct isn't initialized at all so we disclose 2 bytes of uninitialized
stack data. We should clear it before passing it to the user.
Fixes: 48365e485275 ('qlcnic: dcb: Add support for CEE Netlink interface.')
