60b33c133c tiocmget: kill off the passing of the struct file
We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

683d949a7f Bluetooth: Never deallocate a session when some DLC points to it
Fix a bug introduced in commit 9cf5b0ea3a:
function rfcomm_recv_ua calls rfcomm_session_put without checking that
the session is not referenced by some DLC. If the session is freed, that
DLC would refer to deallocated memory, causing an oops later, as shown
in this bug report: https://bugzilla.kernel.org/show_bug.cgi?id=15994

183f732c3f Bluetooth: Fix initial RFCOMM DLC security level
Due to commit 63ce0900 connections initiated through TTYs created with
"rfcomm bind ..." would have security level BT_SECURITY_SDP instead of
BT_SECURITY_LOW. This would cause instant connection failure between any
two SSP capable devices due to the L2CAP connect request to RFCOMM being
sent before authentication has been performed. This patch fixes the
regression by always initializing the DLC security level to
BT_SECURITY_LOW.

fad003b6c8 Bluetooth: Fix inconsistent lock state with RFCOMM
When receiving a rfcomm connection with the old dund deamon a
inconsistent lock state happens. That's because interrupts were already
disabled by l2cap_conn_start() when rfcomm_sk_state_change() try to lock
the spin_lock.

As result we may have a inconsistent lock state for l2cap_conn_start()
after rfcomm_sk_state_change() calls bh_lock_sock() and disable interrupts
as well.
