A more correct reference would be, however, the index of each stream, instead. This patch corrects the check of bitmaps to the stream index. Note that this change doesn't fix anything for now; all existing drivers set up the stream indices properly, hence the loop count is always equal with the stream index. That said, this change is only for consistency.
