Dead code

[ZHJ1237]

cJSON/cJSON.c

Line 1980 in cf97c6f

while (child->next)

I think child->prev always != NULL so that we can not reach code from line 1979 to 1986。
Please check whether it is a dead code or not.

else
        {
            while (child->next)
            {
                child = child->next;
            }
            suffix_object(child, item);
            array->child->prev = item;
        }

Removing it will make cJSON_Utils failed, I will check it and to optimize it when I'm free.
