Merge tag 'usb-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY driver updates from Greg KH:
"Here is the large USB and PHY driver update for 4.14-rc1.
Not all that exciting, a few new PHY drivers, the usual mess of gadget
driver updates and fixes, and of course, xhci updates to try to tame
that beast.
A number of usb-serial updates and other small fixes all over the USB
driver tree are in here as well. Full details are in the shortlog.
All of these have been in linux-next for a while with no reported
issues"
