Ignore this warning. The variable is called wIndex because it corresponds to a field in a USB control transfer, and that's what it's called in the spec. In this case, wIndex is the index into the hub's port array, so it's perfectly valid to use it as an array index here. In general, if checkpatch.pl complains about a variable a patch introduces that's CamelCase, you should pay attention to it. If it's a variable that already present in USB code, it's probably used to match the spec.
