1487 * pccard_loop_tuple() - loop over tuples in the CIS
1488 * @s: the struct pcmcia_socket where the card is inserted
1489 * @function: the device function we loop for
1490 * @code: which CIS code shall we look for?
1491 * @parse: buffer where the tuple shall be parsed (or NULL, if no parse)
1492 * @priv_data: private data to be passed to the loop_tuple function.
1493 * @loop_tuple: function to call for each CIS entry of type @function. IT
1494 * gets passed the raw tuple, the paresed tuple (if @parse is
1495 * set) and @priv_data.
1496 *
1497 * pccard_loop_tuple() loops over all CIS entries of type @function, and
1498 * calls the @loop_tuple function for each entry. If the call to @loop_tuple
1499 * returns 0, the loop exits. Returns 0 on success or errorcode otherwise.
