24 Iterates through the list of known RIO devices. If a RIO device is
25 found with a matching vid and did, the reference count to the device is
26 incrememted and a pointer to its device structure is returned.
27 Otherwise, NULL is returned. A new search is initiated by passing NULL
28 to the from argument. Otherwise, if from is not NULL, searches continue
29 from next device on the global list. The reference count for from is
30 always decremented if it is not NULL.
