[PATCH] pcmcia: reduce client_handle_t usage
Reduce the occurences of "client_handle_t" which is nothing else than a pointer to struct pcmcia_device by now. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
