struct pcmcia_device *p_dev->conf.ConfigBase and .Present are set in almost all PCMICA driver right at the beginning, using the same calls but slightly different implementations. Unfiy this in the PCMCIA core. Includes a small bugfix ("drivers/net/pcmcia/xirc2ps_cs.c: remove unused label") from and Signed-off-by Adrian Bunk <bunk@stusta.de> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
