The same address `i8042_request_irq_cookie' is used in three places for the i8042 request_irq() argument. This means that if someone calls i8042_check_mux() or i8042_check_aux() while the IRQ is in use, the free_irq() call in there will free the wrong IRQ handler. So give all three instances of request_irq() in i8042.c a distinct address by which to identify the IRQ instance. (This is probably a non-bug, because the `check' functions are not called when the device is open, but it is better this way).
