Very sorry, I send two series [1][2] for xhci-mtk, but don't take care
of conficts:

I suppose you will apply [1] firstly, due to [3] is not acked or
reviewed by Rob (I think, only need modify commit message).

Anyway, only one patch [4] is not in usb-testing branch due to
conflicts, I'll fix it and send out, sorry again.
