I still don't understand exactly what you're trying to do.  If you're just
trying to get crypto_user02 to run in more cases, then your patch makes sense.
If on the other hand you're actually trying to get the kernel to instantiate
more algorithms so that their in-kernel self-tests are run, that is *not* the
purpose of crypto_user02; a new test should be written for that purpose.  The
test could try to instantiate all algorithms which have in-kernel self-tests.
