Well, the alternative is to only have a release function somewhere that
calls kfree. Which would be general-purpose "struct device"-kfree
wrapper and would be callable by any piece of code. Where is the
difference to calling kfree directly then? The additional indirection?
No, the release function should be related to a specific object and then
you need the register/unregister functions as well.
