Since commit 8745b9ebccae ("usb: gadget: add super speed support")
ums was no more functional on platform which use dwc2_udc_otg driver.
Remove the speed test in dwc2_gadget_start() to fix it.
Tested on stm32mp157c-ev1 board.
Isn't the speed check correct though ?
I am not sure this speed test is needed.
What is really going on when this fails ?
Since 8745b9ebccae ("usb: gadget: add super speed support"),
driver->speed is now set to USB_SPEED_SUPER in drivers/usb/gadget/composite.c
and this forbids dwc2_udc_otg.c to be registered.
That sounds like a bug in the USB gadget/otg core , no ?
