I had never even thought about that, but I think literally nothing will
happen. The module load will appear to succeed since it's already there,
and no 'fail=N' string will show up in dmesg due to it.

I had considered parsing out the tests, but over time we've had this be
somewhat brittle even with the parsing scripts that are shipped as part
of the kernel, requiring updates every once a while. That didn't seem
great. Having the hostap test know about the expected kunit tests also
seemed awkward, so I settled for just making sure this fails if it
