[PATCH] [Cardman 40x0] Fix udev device creation

Hi!

Please apply this fix for the cm40x0 device drivers.  It's obvious, clean,
affects only those two devices, so I hope it'll make it in 2.6.17-final.

Thanks!

[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>.
