Forcing the driver to be built in looks like a regression, why would we
want to do that?

What's the _byname() adding here given that the name is so generic?  It
feels like if the name ever becomes important then this particular name
is going to be a problem.

Why are you converting this to subsys_initcall()?  This looks like
another regression.
