EPERM means "Operation not permitted", which doesn't reflect the lack of support for AER. EPROTONOSUPPORT (Protocol not supported) is a better choice of error code if the device or its root port lack support for AER. Likewise, EINVAL means "Invalid argument", which is not suitable for cases where the AER error device is missing or unusable. ENODEV and EPROTONOSUPPORT, respectively, fit better.
