tty/8250 Add XR17D15x devices to the exar_handle_irq override
Add XR17D15x devices to the exar_handle_irq override: they have the same extra interrupt register that could fire and never be serviced by the standard handle_irq. Signed-off-by: Matt Schulte <matts@commtech-fastcom.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
