Actually, I did. Just guess how that FIXME came to be.
Hint: the kernel shuts up just as well without it.

No, that was not among the explanations I considered. Although,
come to think of it ... nah, that would really be too weird.

Ahem.

Call me silly and incapable of thinking, but to me it's far from
clear _what_ memory I am supposed to free there. Certainly neither
memory I will still be needing after platform_device_unregister()
nor memory that's being taken care of elsewhere. Between the two,
in my case there's nothing left, so the release function is empty.
If that shows my driver is broken, please explain in what way.

Thanks,
Tilman
