Hi Rob,

Why do you need this patch? You're moving the wakeup handling from the
PCI device to the bridge. The bridge device is not PCI interrupts, but
a platform device so this function doesn't matter.

because it's possible we have multiple PCI devices with individual WAKE# 
interrupt.

so Brian suggested we may need to support both of PCI device wakeup 
handling and the bridge wakeup handling in the pci core(as the ACPI) :)
