- * lpfc_aer_support_init - Set the initial adapters aer support flag

- * Description:
- * If val is in a valid range [0,1], then set the adapter's initial
- * cfg_aer_support field. It will be up to the driver's probe_one
- * routine to determine whether the device's AER support can be set
- * or not.
- *
- * Notes:
- * If the value is not in range log a kernel error message, and
- * choose the default value of setting AER support and return.
- *
- * Returns:
- * zero if val saved.
- * -EINVAL val out of range
