    The compiler complains about variables that are set, but never used:
    * intX variables in exar_handle_irq
      drivers/tty/serial/8250/8250_port.c:1864:34: warning: variable ‘int3’ set but not used [-Wunused-but-set-variable]
    * val variable in pci_quatech_wqopr
      drivers/tty/serial/8250/8250_pci.c:1139:10: warning: variable ‘val’ set but not used [-Wunused-but-set-variable]
    
    And about a shadow variable:
    * tmout in wait_for_xmitr is defined twice with the same type. Both of
      them are also initialized before use.
    
    Remove all of them.
