I don't think you need to specify the "default to avr0" in the comment, because it's obvious that's what the code does (and only then in the unusual case of an unknown value).

Also, the second sentence about "report unknown" is largely irrelevant here, because this area of code is about assigning features. The "unknown" reporting is handled in a completely different place and could in theory change.
