Is the debug message necessary even when AER is not available?
At least current code doesn't output such strings when pci=noaer,
since AER service driver is not loaded.

if (pci_aer_available()) {
	if (pcie_aer_get_firmware_first(port))
		dev_dbg(&port->dev, "PCIe errors handled by BIOS.\n");
	else
		flags |= OSC_PCI_EXPRESS_AER_CONTROL;
}

Thanks,
