net/ipv6: Remove ip_idx arg to in6_dump_addrs
ip_idx is always 0 going into in6_dump_addrs; it is passed as a pointer to save the last good index into cb. Since cb is already argument to in6_dump_addrs, just save the value there. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
