From: Maciej Żenczykowski <m...@google.com>
s->local.data is a pointer to a field of a non-NULL struct, and hence
cannot be NULL, thus comparing it to 0 is always false, and thus the
return is always false.
Presumably this was meant to be a check whether s->local.data[0] (which
I believe stores af_packet protocol) is 0, ie. ANY.

Fixes:
ss.c:1018:37: error: comparison of array 's->local.data' equal to a null
pointer is always false [-Werror,-Wtautological-pointer-compare]
return s->lport == 0 && s->local.data == 0;
