+Subject: [PATCH] xhci: quirks: add link TRB quirk for VL805
+
+The VL805 controller can't cope with the TR Dequeue Pointer for an endpoint
+being set to a Link TRB. The hardware-maintained endpoint context ends up
+stuck at the address of the Link TRB, leading to erroneous ring expansion
+events whenever the enqueue pointer wraps to the dequeue position.
+
+If the search for the end of the current TD and ring cycle state lands on
+a Link TRB, move to the next segment.
+
+See: https://github.com/raspberrypi/linux/issues/3919
