    Bluetooth: Reject SCO when hci connection timeouts · 93796fa6
    Claudio Takahasi authored
    This patch sends Reject Synchronous Connection Request Command when
    hci_conn_timeout is triggered, and the SCO connection is in BT_CONNECT2
    state. It prevents inconsistency if the remote host doesn't implement
    properly the timeout for the connection request, and it removes the
    connection reference left when the socket is closed for incoming SCO
    connections.
