Merge tag 'usb-4.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB fixes from Greg KH: "Here is a number of different USB fixes for 4.11-rc2. Seems like there were a lot of unresolved issues that people have been finding for this subsystem, and a bunch of good security auditing happening as well from Johan Hovold. There's the usual batch of gadget driver fixes and xhci issues resolved as well.
