This series fixes a couple of driver issues handling ClearFeature(halt) request: 1) A function driver often uses set_halt() to reject a class driver protocol command. After set_halt(), the endpoint will be stalled. It can queue new requests while the endpoint is stalled. However, dwc3 currently drops those requests after CLEAR_STALL. The driver should only drop started requests. Keep the pending requests in the pending list to resume and process them after the host issues ClearFeature(Halt) to the endpoint. 2) DWC3 should issue CLEAR_STALL command _after_ END_TRANSFER command completes.
