Merge tag 'usb-4.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 

Pull USB fixes from Greg KH:
 "Here are a bunch (65) of USB fixes for 4.7-rc4.  Sorry about the
  quantity, I've been slow in getting these out.

  The majority are the "normal" gadget, musb, and xhci fixes, that we
  all are used to.  There are also a few other tiny fixes resolving a
  number of reported issues that showed up in 4.7-rc1.

  All of these have been in linux-next"
