Joerg Mayer 8f3ad91905 Fix some warnings/errors of type 
git/epan/dissectors/packet-a21.c:478:25: error: 'item' was marked unused but was used
      [-Werror,-Wused-but-marked-unused]
        proto_item_append_text(item, "%s", val_to_str_const(event_id, a21_event_vals, "Unknown"));
                               ^
Added manual change id because file-jpeg.c forced the use of commit -n
