Subject: tls: rx: assume crypto always calls our callback
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1c699ffa48a15710746989c36a82cbfb07e8d17f;p=linux.git

tls: rx: assume crypto always calls our callback

If crypto didn't always invoke our callback for async
we'd not be clearing skb->sk and would crash in the
skb core when freeing it. This if must be dead code.
