| |
For stream capable endpoints, uas layer can queue mulpile requests on single ep with different stream ids. So, there can be multiple pending requests waiting to be transferred. This patch changes the code to check for any pending requests waiting to be transferred on ep started_list and calls __dwc3_gadget_kick_transfer() if any.
