 442  * tree should return this value.  BUS_PROBE_LOW_PRIORITY are for drivers that
 443  * have special requirements like when there are two drivers that support
 444  * overlapping series of hardware devices.  In this case the one that supports
 445  * the older part of the line would return this value, while the one that
 446  * supports the newer ones would return BUS_PROBE_DEFAULT.  BUS_PROBE_GENERIC
 447  * is for drivers that wish to have a generic form and a specialized form,
 448  * like is done with the pci bus and the acpi pci bus.  BUS_PROBE_HOOVER is
 449  * for those busses that implement a generic device place-holder for devices on
