---------------------------------------------
bluepush/3213 is trying to acquire lock:
(sk_lock-AF_BLUETOOTH){--..}, at: [<f8978c80>]
l2cap_sock_bind+0x40/0x100 [l2cap]
but task is already holding lock:
(sk_lock-AF_BLUETOOTH){--..}, at: [<f894a31e>]
rfcomm_sock_connect+0x3e/0xe0 [rfcomm]
other info that might help us debug this:
2 locks held by bluepush/3213:
#0: (sk_lock-AF_BLUETOOTH){--..}, at: [<f894a31e>]
rfcomm_sock_connect+0x3e/0xe0 [rfcomm]
#1: (rfcomm_mutex){--..}, at: [<f8947556>] rfcomm_dlc_open+0x26/0x60 [rfcomm]
