Subject: [PATCH 3.12 113/142] cifs: fix erroneous return value

From: Anton Protopopov <a.s.protopopov@...il.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 4b550af519854421dfec9f7732cdddeb057134b2 upstream.

The setup_ntlmv2_rsp() function may return positive value ENOMEM instead
of -ENOMEM in case of kmalloc failure.
