Seems to work correctly.
Still... given this paragraph found in Documentation/process/maintainer-netdev.rst:
|Netdev remains skeptical about promises of all "auto-cleanup" APIs,

and given my solution is way simpler, I tend to also prefer it over yours.
But I'm not the maintainer nor even a significant contributor here so as
long as the issue is fixed I won't mind.
