The DPC driver clears AER fatal status for the port that reported the error, but not for the downstream device that deteced the error. The current recovery code only clears non-fatal AER status, leaving fatal status bits set in the error device.
Use pci_aer_raw_clear_status() to clear both fatal and non-fatal error status in the error device, ensuring all AER status bits are properly cleared after recovery.
