IMHO you should be free to bump the module reference count up and down
as you wish, and be able to read the module reference count.

If you make that assumption, then it becomes possible to use the module
ref count as an internal reference counter, for device opens or
something like that.

In i810_rng.c it eliminated the need for an additional reference
count... until I attempted to compile it into the kernel instead of as a
module, for the first time :)
