    TTY: call tty_port_destroy in the rest of drivers · 191c5f10
    Jiri Slaby authored
    After commit "TTY: move tty buffers to tty_port", the tty buffers are
    not freed in some drivers. This is because tty_port_destructor is not
    called whenever a tty_port is freed. This was an assumption I counted
    with but was unfortunately untrue. So fix the drivers to fulfil this
    assumption.
    
    To be sure, the TTY buffers (and later some stuff) are gone along with
    the tty_port, we have to call tty_port_destroy at tear-down places.
    This is mostly where the structure containing a tty_port is freed.
    This patch does exactly that -- put tty_port_destroy at those places.
