This is problematic.

Why do you have the driver "own" the controller?  What is dev for,
there's already a struct device within the controller.  Same for slave,
what is it?

You have 3 struct devices here, which one controls the lifecycle of the
object (hint, I know the answer, but I think it's wrong...)

thanks,
