Patch in this message |
-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>.
