Not as far as I understand it, it's more about making error handling and
unregistration code less error prone by automating the freeing of
things when a device goes away or probe() fails.  The managed versions
wrap the unmanaged allocators but don't generally otherwise change the
interface except by adding a struct device.  Unless I'm missing
something, of course.
