    common: hash: zero end the string instead of the pointer · 8b9cc866

    if algo->digest_size is zero nothing is set in the str_output
    buffer. An attempt is made to zero end the buffer, but the
    pointer to the buffer is set to zero instead. I am unaware if
    it causes any actual problems, but solves the following warning:
    
    common/hash.c:217:13: warning: expression which evaluates to zero treated as
    a null pointer constant of type 'char *' [-Wnon-literal-null-conversion]
                    str_ptr = '\0';
