Thanks for taking the time to send a patch.
Why do you think including a file will fix this? That error is usually
the user's fault for trying to use insmod which doesn't check module
dependencies.
The advice I usually give is to try modprobe instead, does the problem
still occur without this patch and just using modprobe?
