Pull staging fixes from Greg KH:
 "Here are some small staging driver fixes for 5.5-rc6.

  Nothing major here, just some small fixes for a comedi driver, the
  vt6656 driver, and a new device id for the rtl8188eu driver.

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