Kai-Heng Feng 75c47c790f PCI/DPC: Disable DPC service on suspend ... If the link is powered off during suspend, electrical noise may cause errors that trigger DPC. If the DPC interrupt is enabled and shares an IRQ with PME, that causes a spurious wakeup during suspend. Disable DPC triggering and the DPC interrupt during suspend to prevent this. Clear DPC interrupt status before re-enabling DPC interrupts during resume so we don't get an interrupt for errors that occurred during the suspend/resume process.
