For some reason I've dropped, from the previous cover letter, the
phrase mentioning that this patchset depends on this patchset:

https://lore.kernel.org/all/7ed0f2779829f4e63b69d8cf5cedda9f849996bc.1756372805.git.andrea.porta@suse.com/

which contains the schema. If you apply it as prerequisite, warnings
should disappear.

Many thanks,
Andrea
