[PATCH 14/22] [PATCH] [Cardman 40x0] Fix udev device creation

[Chris Wright <chrisw@sous-sol.org>]

-stable review patch.  If anyone has any objections, please let us know.
------------------

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>.
