Subject: [PATCH 4.4 26/72] netfilter: ctnetlink: Make some parameters integer to avoid enum mismatch

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

------------------

From: Matthias Kaehlcke <mka@...omium.org>

commit a2b7cbdd2559aff06cebc28a7150f81c307a90d3 upstream.

Not all parameters passed to ctnetlink_parse_tuple() and
ctnetlink_exp_dump_tuple() match the enum type in the signatures of these
functions. Since this is intended change the argument type of to be an
unsigned integer value.
