Merge tag 'usb-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY updates from Greg KH:
 "Here is the big USB and phy driver patch set for 4.19-rc1.

  Nothing huge but there was a lot of work that happened this
  development cycle:

   - lots of type-c work, with drivers graduating out of staging, and
     displayport support being added.

   - new PHY drivers

   - the normal collection of gadget driver updates and fixes

   - code churn to work on the urb handling path, using irqsave()
     everywhere in anticipation of making this codepath a lot simpler in
     the future.

   - usbserial driver fixes and reworks

   - other misc changes

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