503 * have special requirements like when there are two drivers that support
504 * overlapping series of hardware devices. In this case the one that supports
505 * the older part of the line would return this value, while the one that
506 * supports the newer ones would return BUS_PROBE_DEFAULT. BUS_PROBE_GENERIC
507 * is for drivers that wish to have a generic form and a specialized form,
508 * like is done with the pci bus and the acpi pci bus. BUS_PROBE_HOOVER is
509 * for those busses that implement a generic device place-holder for devices on
510 * the bus that have no more specific river for them (aka ugen).
511 * BUS_PROBE_NOWILDCARD or lower means that the device isn't really bidding
512 * for a device node, but accepts only devices that its parent has told it
513 * use this driver.
