4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Florian Westphal <f...@strlen.de>
commit dbc3617f4c1f9fcbe63612048cb9583fea1e11ab upstream.
nfnetlink_bind request_module()s all the time as nfnetlink_get_subsys()
shifts the argument by 8 to obtain the subsys id.
So using type instead of type << 8 always returns NULL.
Fixes: 03292745b02d11 ("netlink: add nlk->netlink_bind hook for module
auto-loading")
