Merge tag 'usb-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here is the big set of USB patches for 5.4-rc1.

  Two major chunks of code are moving out of the tree and into the
  staging directory, uwb and wusb (wireless USB support), because there
  are no devices that actually use this protocol anymore, and what we
  have today probably doesn't work at all given that the maintainers
  left many many years ago. So move it to staging where it will be
  removed in a few releases if no one screams.

  Other than that, lots of little things. The usual gadget and xhci and
  usb serial driver updates, along with a bunch of sysfs file cleanups
  due to the driver core changes to support that. Nothing really major,
  just constant forward progress.

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