[Cardman 40x0] Fix udev device creation
This patch corrects the order of the calls to register_chrdev() and pcmcia_register_driver(). Now udev correctly creates userspace device files /dev/cmmN and /dev/cmxN respectively. Based on an earlier patch by Jan Niehusmann <jan@gondor.com>. Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
