Hello list,

There is a "ttyS1 irq is -1" problem observed on tiger4 which cause
the serial port broken.
It is because that there is __no__ ACPI IRQ resource assigned for the
serial port. So the value of the IRQ for the port is never changed
since it got initialized to -1. The attached patch falls back to the
"no irq" hack for this case. It works for me. Please review and test.
