I am not sure that this patch is good. Currently, this patch does not make any problem. However, I prefer to keep checking codes unless it makes a lot of burden. This is because we cannot ensure that flow of codes will not change in the future. However, if you think that it can be ensured that the problem will not happen in the future, please merge this patch.
