usb: dwc3: ep0: use dwc3_request for ep0 requsts instead of usb_request
Instead of special functions and shortcuts for sending our internal answers to the host we started doing what the gadget does and used the public API for this. Since we only were using a few fields the usb_request was enough. Later added the list handling in order to synchronize the host / gadget events and now we require to have the dwc3_request struct around our usb_request or else we touch memory that does not belong to us. So this patch does this. Reported-by: Partha Basak <p-basak2@ti.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
