I think I managed to use the right function arguments. My current
solution looks like this:

static inline int l2cap_information_rsp(struct l2cap_conn *conn, struct
l2cap_cmd_hdr *cmd, u8 *data)
{
	[...]
	struct sock *sk;
	[...]
	if (!(sk =3D l2cap_get_chan_by_ident(&conn->chan_list, cmd->ident)))
		return 0;
	[...]
	l2cap_pi(sk)->info_mtu =3D __le16_to_cpup((__le16 *) rsp->data);
	[...]
}

I tried to test this with two Siemens mobilephones (S55 and S75) and a
Windows XP machine, but none of them seems to make use of any
information requests at all ...=20
Perhaps somebody knows of a device that tries to inform itself about
it's remote partner before sending requests?
