[PATCH v8 2/3] PCI/AER: Disable AER service on suspend

2024-04-15 Thread Kai-Heng Feng
When the power rail gets cut off, the hardware can create some electric noise on the link that triggers AER. If IRQ is shared between AER with PME, such AER noise will cause a spurious wakeup on system suspend. When the power rail gets back, the firmware of the device resets itself and can create
