Add a condition of set_address and set_configuration to check
if the request is standardized.

Hi!
What do you say we reorder the check a little:

if ((setup->requesttype & USB_TYPE_MASK) == USB_TYPE_STANDARD) {
	if (setup->request == USB_REQ_SET_ADDRESS)
		return xhci_address_device(udev, root_portnr);

	if (setup->request == USB_REQ_SET_CONFIGURATION)
		...
}

Also, I suspect this sort of fix needs to be applied to at least dwc3 ep0.c,
r8a66597-hcd.c and musb_hcd.c as well.

Paging Hans so he can share his visdom too :)

I don't have another board in my hand, so I can't verify the other xhci host controller.

But I have confirmed this patch in xhci.c actually can fix errors while  the the request type is USB_REQ_SET_ADDRESS or USB_REQ_SET_CONFIGURATION in USB vendor command.

Hi Hans,

Do you have any comments?

Thanks

That's fine, just fixing this problem everywhere is enough and the people
who have the controller can test it themselves.
