Mostly expanded on this in my previous reply of patch 1, but yes, I
agree. Should have pushed back on review of V1 where moving it to
VERSION_GENERIC was suggested. The one alternative is to still make it
generic, but give it a better name to make it clear that it is a
codename. Still, I don't know if that is generally helpful, happy to
keep it driver only.
