I can't seem to get BNEP working, and I have a feeling it has got to
do something with this patch.
I actually hit the error condition NULL @ [ 8882.843017] chan->scid 64
[ 8882.845977] Bluetooth: parent is NULL
[ 8882.850067] conn e53e5e00, code 0x03, ident 0x66, len 8
[ 8882.855895] code 0x03
[ 8882.858581] hci0: type 2 len 21

which is at +//
parent->sk_data_ready(parent, 0);
+                                       if (parent) {
+                                               BT_ERR("hitting condition @\
+                                               %d", __LINE__);
+                                               parent->sk_data_ready(parent,
+                                               0);
+                                       } else {
+                                               BT_ERR("parent is NULL");
+                                       }

my l2cap_config_req does say this now,
@@ -2524,7 +2525,7 @@ static inline int l2cap_config_req(struct
l2cap_conn *conn, struct l2cap_cmd_hdr

        sk = chan->sk;

-       if (chan->state != BT_CONFIG) {
+       if (chan->state != BT_CONFIG && sk->sk_state != BT_CONNECT2) {
                struct l2cap_cmd_rej rej;


However, I can seem to connect because of the following reason,

Any suggestions ??
