ipv6: Remove redundant dst NULL check in ip6_dst_check
As the only path leading to ip6_dst_check makes an indirect call through dst->ops, dst cannot be NULL in ip6_dst_check. This patch removes this check in case it misleads people who come across this code. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
