I picked these back to my chromeos-3.14 kernel (with many many dwc2
backports) and I confirmed that I can still compile the kernel, boot
it, and use USB.  I also confirmed no warnings were introduced for me.
I'm only testing HOST, not gadget mode.

I also reviewed the code and agree that it looks good.  Thanks!
