I'm not sure I'd do either for this trivial case, but it might make sense where the cleanup logic is more complex?

    void* p1 = malloc(...);
    void* p2 = malloc(...);
    void* p3 = malloc(...);

    if(p1 && p2 && p3)
      return {p1, p2, p3};

    free(p3);
    free(p2);
    free(p1);
    return NULL;
