61# A helper method for implementing probe methods for PnP compatible
62# drivers. The driver calls this method with a list of PnP ids and
63# descriptions and it returns zero if one of the ids matches or ENXIO
64# otherwise.
65#
66# If the device is not plug-and-play compatible, this method returns
67# ENOENT, allowing the caller to fall back to heuristic probing
68# techniques.
