X-Git-Tag: omap-for-v3.8/fixes-for-merge-window-v4-signed~45^2~221

ipv4: ipmr: various fixes and cleanups

1) ip_mroute_setsockopt() & ip_mroute_getsockopt() should not
   access/set raw_sk(sk)->ipmr_table before making sure the socket
   is a raw socket, and protocol is IGMP

2) MRT_INIT should return -EINVAL if optlen != sizeof(int), not
   -ENOPROTOOPT

3) MRT_ASSERT & MRT_PIM should validate optlen

4) " (v) ? 1 : 0 " can be written as " !!v "
