rio_get_device - Begin or continue searching for a RIO device by
struct rio_dev * rio_get_device (u16 vid, u16 did,
struct rio_dev * from);
vid RIO vid to match or RIO_ANY_ID to match all vids
did RIO did to match or RIO_ANY_ID to match all dids
from Previous RIO device found in search, or NULL for new search
Iterates through the list of known RIO devices. If a RIO device is
found with a matching vid and did, the reference count to the device is
incrememted and a pointer to its device structure is returned.
Otherwise, NULL is returned. A new search is initiated by passing NULL
to the from argument. Otherwise, if from is not NULL, searches continue
from next device on the global list. The reference count for from is
always decremented if it is not NULL.
