Supicious code in chtls_io

Hi all,

While doing some static analysis I came across the following piece of code at drivers/crypto/chelsio/chtls/chtls_io.c:1203:

1203 if (!size)
1204 break;
1205
1206 if (unlikely(ULP_SKB_CB(skb)->flags & ULPCB_FLAG_NO_APPEND))
1207 push_frames_if_head(sk);
1208 continue;
1209
1210 set_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
1211 }

The issue is that in the code above, set_bit is never reached due to the 'continue' statement at line 1208.

I wonder if the actual intention of the code was something like this:

drivers/crypto/chelsio/chtls/chtls_io.c +3 -2

+               }
 
                set_bit(SOCK_NOSPACE, &sk->sk_socket->flags);
        }

What do you think?

I can send a proper patch for this.

Thanks
