From c0a9ab93f49a3d2508c95d0ca1a01c1089983731 Mon Sep 17 00:00:00 2001
From: Yasuyuki KOZAKAI <yasuyuki@netfilter.org>
Date: Tue, 24 Jul 2007 06:02:05 +0000
Subject: Fixes warning on compilation of iptables matches/targets

This changes the type of arguments as follows
- ipt_ip * -> void *
- ipt_entry * -> void *

This patch doesn't change multiport, DNAT, SNAT, MASQUERADE, REDIRECT
because these need more changes (casting void * variable with intended type)
