Deadlock in bluetooth/sco.c

Hi,

I've found some possible deadlock in net/bluetooth/sco.c - version
2.6.28 (probably this code is in newer versions too).
Could someone confirm this? Thank you.


net/bluetooth/sco.c
==============

function sco_conn_ready: (conn <- sk)
-------------------------------------
lockig sco_conn_lock(conn) at line 796
bh_lock_sock(sk)  at line 800

function  sco_conn_del: (sk <- conn)
---------------------------------
bh_lock_sock(sk); at 154
calling function sco_chan_del(sk, err); at line 156
       where at line 767 is sco_conn_lock(conn);
