John Keeping 92ef98a4ca usb: dwc2: gadget: initialize max_speed from params ... DWC2 may be paired with a full-speed PHY which is not capable of high-speed operation. Report this correctly to the gadget core by setting max_speed from the core parameters. Prior to commit 5324bad66f ("usb: dwc2: gadget: implement udc_set_speed()") this didn't cause the hardware to be configured incorrectly, although the speed may have been reported incorrectly. But after that commit params.speed is updated based on a value passed in by the gadget core which may set it to a faster speed than is supported by the hardware. Initialising the max_speed parameter ensures the speed passed to dwc2_gadget_set_speed() will be one supported by the hardware.
