The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.

Here is the backport, along with 2a499b452952 ("usb: dwc3: ulpi: fix checkpatch warning") which makes backporting easy.
