Merge branch 'master' of git://1984.lsi.us.es/nf-next
Pablo says: ==================== The following four patches provide Netfilter fixes for the cthelper infrastructure that was recently merged mainstream, they are: * two fixes for compilation breakage with two different configurations: - CONFIG_NF_NAT=m and CONFIG_NF_CT_NETLINK=y - NF_CONNTRACK_EVENTS=n and CONFIG_NETFILTER_NETLINK_QUEUE_CT=y * two fixes for sparse warnings. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
