Roger Quadros b0434aaec7 usb: dwc3: don't set gadget->is_otg flag ... commit c09b73cfac2a9317f1104169045c519c6021aa1d upstream. This reverts commit 6a4290cc28 ("usb: dwc3: gadget: set the OTG flag in dwc3 gadget driver.") We don't yet support any of the OTG mechanisms (HNP/SRP/ADP) and are not setting gadget->otg_caps, so don't set gadget->is_otg flag. If we do then we end up publishing a OTG1.0 descriptor in the gadget descriptor which causes device enumeration to fail if we are connected to a host with CONFIG_USB_OTG enabled.
