195 * not use the 'irq' fields. However, an earlier developer
196 * misunderstood the meaning of the 'irq' fields and the driver did
197 * not support the standard fields. To avoid invalidating existing
198 * user documentation, we report and accept changes through either the
199 * standard or 'irq' fields. If both are changed at the same time, we
200 * prefer the standard field.
