   2  *      Slot structures for PC-CARD interface.
   3  *      Each slot has a controller specific structure
   4  *      attached to it. A slot number allows
   5  *      mapping from the character device to the
   6  *      slot structure. This is separate to the
   7  *      controller slot number to allow multiple controllers
   8  *      to be accessed.
