    pcmcia: add new CIS access helpers · 91284224
    Dominik Brodowski authored
    As a replacement to pcmcia_get_{first,next}_tuple() and
    pcmcia_get_tuple_data(), three new -- and easier to use --
    functions are added:
    - pcmcia_get_tuple() to get the very first CIS entry of one
    - pcmcia_loop_tuple() to loop over all CIS entries of one type.
    - pcmcia_get_mac_from_cis() to read out the hardware MAC address
      from CISTPL_FUNCE.
    Only a handful of drivers need these functions anyway, as most
    CIS access is already handled by pcmcia_loop_config(), which
    now shares the same backed (pccard_loop_tuple()) with
    A pcmcia_get_mac_from_cis() bug noted by Komuro
    <komurojun-mbn@nifty.com> has been fixed in this revision.
