pcmcia: convert net pcmcia drivers to use new CIS helpers
Use the new CIS helpers in net pcmcia drivers, which allows for a few code cleanups. This revision does not remove the phys_addr assignment in 3c589_cs.c -- a bug noted by Komuro <komurojun-mbn@nifty.com> CC: David S. Miller <davem@davemloft.net> CC: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
