I believe that some maintainer have a different view on this kind of
patches compared to you, adding new device id would be material for
stable, or this specific issue preventing module auto loading.

I noticed that this specific view is not new from you, see
https://lore.kernel.org/all/CY54PJM8KY92.UOCXW1JQUVF7@suppilovahvero/.

With that said, I am ok with it.

Do you want a new patch version without Fixes/Cc:stable tags or you can
remove those while applying?
