pcmcia: add new CIS access helpers
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 type. - 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 pcmcia_loop_tuple(). A pcmcia_get_mac_from_cis() bug noted by Komuro <komurojun-mbn@nifty.com> has been fixed in this revision. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
