No, more like the open of a sysfs file could also grab a refcount on the
module. All it would take is a custom open/close method for sysfs files.
Now I have no clue how to do that, but that's another issue.

Also, I really don't see the point. With modular PMUs there's always
races against unload, just don't do that or live with it.
