If you're going to do this, you might as well also remove the conditional
statement here entirely. I.e. just have the function be this:
return (asoc->base.bind_addr.port == ntohs(laddr->v4.sin_port)) &&
sctp_bind_addr_match(&asoc->base.bind_addr, laddr,
sctp_sk(asoc->base.sk)));
You might also look into makeing it inline, though it doesn't appear in any hot
paths so thats likely overkill
