[01/11] If ACPI doesn't find an irq listed, don't accept 0 as a valid PCI irq.

[01/11] If ACPI doesn't find an irq listed, don't accept 0 as a valid PCI irq.

-stable review patch.  If anyone has any objections, please let us know.

------------------

If ACPI doesn't find an irq listed, don't accept 0 as a valid PCI irq.
That zero just means that nothing else found any irq information either.
