int eeh_dn_check_failure (struct device_node * dn, struct pci_dev * dev);
dn device node dev pci device, if known
Check for an EEH failure for the given device node. Call this routine if the result of a read was all 0xff's and you want to find out if this is due to an EEH slot freeze. This routine will query firmware for the EEH status.
Returns 0 if there has not been an EEH error; otherwise returns a non-zero value and queues up a solt isolation event notification.
It is safe to call this routine in an interrupt context.
