Looks like I missed, the case statement, thus, idx will be intact. Please ignore my previous comment.
However, as mentioned in previous patch, we can also make *i* as unsigned short and that should IMO remove the requirement of cast.
But again, this works as well. I'm fine with either. Thanks and sorry for the confusion.
