Pull USB updates from Greg KH: "Here's the big USB and PHY patchset for 4.3-rc1. As usual, the majority of the changes are in the USB gadget portion of the tree, lots of little changes all over the place for bugs and new hardware. Other than that, the normal mix of new hardware support and bugfixes.
