+Subject: xhci: Make sure xhci handles USB_SPEED_SUPER_PLUS devices.
+
+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit 0caf6b33452112e5a1186c8c964e90310e49e6bd upstream.
+
+In most cases the devices with the speed set to USB_SPEED_SUPER_PLUS
+are handled like regular SuperSpeed devices.
