cgeb_exit is only used through module_exit(). So I guess it could be
marked __exit, right?

The comment at the top of this file states the license is GPL v2. The
MODULE_LICENSE() macro states, according to include/linux/module.h, that
the license is GPL v2 or later. So I think one of these two needs to
change.

I spotted the same license mismatch in 2/4, 3/4 and 4/4.

Thanks,
