While the return value can be NULL (so the *check* for NULL is a bit
obscure but theoretically "it could happen"), the *initialization* is
just bogus - this is not a pass-by-reference pointer that could be set
or not, but a function return value, which is always set (possibly
to NULL), and always overwrites whatever you init it with.
