[PATCH v4 2/3] PCI/AER: Disable AER interrupt on suspend

2023-04-23 Thread Kai-Heng Feng
PCIe service that shares IRQ with PME may cause spurious wakeup on system suspend. PCIe Base Spec 5.0, section 5.2 "Link State Power Management" states that TLP and DLLP transmission is disabled for a Link in L2/L3 Ready (D3hot), L2 (D3cold with aux power) and L3 (D3cold), so we don't lose much he
