    Subject[PATCH 5.3 050/180] usb: dwc3: gadget: Clear started flag for non-IOC
    Date
    From: Thinh Nguyen <Thinh.Nguyen@synopsys.com>

    commit d3abda5a98a18e524e17fd4085c9f4bd53e9ef53 upstream.

    Normally the END_TRANSFER command completion handler will clear the
    DWC3_EP_TRANSFER_STARTED flag. However, if the command was sent without
    interrupt on completion, then the flag will not be cleared. Make sure to
    clear the flag in this case.
