The functions and variables touched by this commit can be static,
as they are only used within the same unit. This in turn addresses
the absence of declarations that violates Rule 8.4.

I'm happy with the code changes here and also in patch 3, but please
make the titles meaningful (in patch 3 the prefix also wants to be
more specific). As mentioned, the Misra rule is secondary here, and
hence doesn't need to be present in the titles.
