Subject: Null pointer dereference in pti_exit()

Hi

We have this bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=783561

Crash when someone load module and do not have actual pti device.
Then misc_deregister(&pti_char_driver) called from pti_exit() will be
done without misc_register(&pti_char_driver), which is called from
pti_pci_probe().

It is not super critical issue since if somebody who do not have
pti device have no reason to load modules, but I guess would be
good to fix this.

Thanks
Stanislaw
