Subject: linux-next: build warning after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

net/ipv4/igmp.c: In function 'igmp_group_added':
net/ipv4/igmp.c:1227:14: warning: unused variable 'net' [-Wunused-variable]
  struct net *net = dev_net(in_dev->dev);
              ^
net/ipv4/igmp.c: In function 'ip_mc_inc_group':

  struct net *net = dev_net(in_dev->dev);
              ^
