As we spoke earlier, and for the record, devm will automate the
lifetime of a resource, taking care to relinquish it when the driver
is unloaded.

I feel better with an explicit `Drop` implementation, which is why
the devm versions were not chosen. IMHO, the problem it was
designed to solve often simply does not apply to Rust code.
