Compressed to one sentence, it is driver core plumbing to allow bus device
private data (and registration data) to represent their lifetime being tied=
 to
the device / driver lifecycle with native Rust lifetimes.

Drivers can take advantage of this subsequently; for reference see the nova=
-core
changes at the end of this series.

Thanks -- as mentioned, it is driver core plumbing, so eventually I'll take=
 it
through the driver core tree.
