The firmware code uses the `Device` structure, but it doesn't create a
reference from a raw pointer.

This function should probably only ever be called from bus abstractions. I
thought the PHY layer needed this urgently (which also was the reason we merged
it already), so I'd expect the PHY code to use it.

Though, they might just use `as_ref`.
