For me it would be useful to know why this is the case. I looked at the
dummy regulator driver and it still has a `probe` function. Presumably,
because it has to wait until other resources are usable and that is the
case once `probe` gets called. But doesn't the same hold for Rust? Or
are Rust modules loaded later than C modules? Because if I were to
rewrite the regulator driver in Rust (assuming we had the abstractions),
the `probe` code would be put into the `Module::init` function, right?
Or am I missing something?

Thanks!
