Original isp116x-hcd code prepared multiple PTDs for longer than 16 byte transfers for one endpoint. That is unnecessary because the ISP116x is able to split long data from one PTD into multiple transactions based on the buffer size of the endpoint. It also caused serious problems if the endpoint NAKed some of the transactions. In that case ISP116x wouldn't notice that the other PTDs were for the same endpoint and would try the other PTDs possibly out of order. That would break the whole transfer.
This patch makes isp116x_submit_job to use one PTD for one transfer.
