Merge tag 'usb-4.15-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY fixes from Greg KH:
 "Here are a number of small USB and PHY driver fixes for 4.15-rc6.

  Nothing major, but there are a number of regression fixes in here that
  resolve issues that have been reported a bunch. There are also the
  usual xhci fixes as well as a number of new usb serial device ids.

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