    So all I need is this?

    static void ehv_bc_tty_hangup(struct tty_struct *ttys)
    struct ehv_bc_data *bc = ttys->driver_data;


    I've noticed that some drivers flush their transmit buffers before calling
    tty_port_hangup(), but some others don't. Should I do this too? I don't know
    if hangup should be as quick as possible.
