Sorry, I don't think that came out the way I meant it. I don't really
think we are consistent on this point across the kernel, and I don't
feel very strongly about the point, so I was just looking to follow
the path of least resistance. (I also just assumed Rob would keep us
consistent within drivers/of/.)

I figure if we are running unit tests from the test runner script or
from an automated system, you won't be hunting for dependencies for a
single test every time you want to run a test, so select doesn't make
it easier to configure in most imagined use cases.

KUNIT hypothetically should not depend on anything, so select should
be safe to use.

On the other hand, if we end up being wrong on this point and KUnit
gains widespread adoption, I would prefer not to be in a position
where I have to change a bunch of configs all over the kernel because
this example got copied and pasted.
