Subject: [PATCH 0163/1085] usb: xhci: drop and add the endpoint context in
xhci_fixup_endpoint()
Setting both the Drop and Add bits on the input context prevents the
corruption of split transactions seen with the BCM2711 XHCI controller,
which is a dwc3 variant.
This is a downstream feature that allows usbhid to restrict polling
intervals on mice and keyboards, and was only tested on a VL805 which
didn't complain about the fact the endpoint got added twice.
