NAME
       rio_get_comptag - Begin or continue searching for a RIO device by component tag

SYNOPSIS
       struct rio_dev * rio_get_comptag(u32 comp_tag, struct rio_dev * from);

ARGUMENTS
       comp_tag
           RIO component tag to match

       from
           Previous RIO device found in search, or NULL for new search

DESCRIPTION
       Iterates through the list of known RIO devices. If a RIO device is found with a matching
       comp_tag, 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.
