You can just review the code.  There is only one caller.

Btw, it's fine to have unnecessary NULL checks so long as they're done
consistently.  Generally, we prefer people not add unnecessary code,
but if it makes you feel safer, most maintainers aren't going to nit-pick
you about it.  If you are doing the work then you get some say your own
code.
