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.
