I think MiscDevice should ideally use the generic `Registration` type from [1].

I see that you use `InPlaceModule` now, which is fine. But since this is just a
sample, we could probably afford to wait until the generic type lands.

Also, there was a comment about how we can make use of the `dev_*` macros.

I really think we should fix those before we land a sample driver. It's gonna
be hard to explain people later on that they shouldn't do what the example
does...
