Merge tag 'usb-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY updates from Greg KH:
 "Here is the big patchset of USB and PHY driver updates for 4.13-rc1.

  On the PHY side, they decided to move files around to "make things
  easier" in their tree. Hopefully that wasn't a mistake, but in
  linux-next testing, we haven't had any reported problems.

  There's the usual set of gadget and xhci and musb updates in here as
  well, along with a number of smaller updates for a raft of different
  USB drivers. Full details in the shortlog, nothing really major.

  All of these have been in linux-next for a while with no reported
  issues"
