Merge tag 'usb-5.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are some small USB driver fixes for 5.2-rc5

  Nothing major, just some small gadget fixes, usb-serial new device
  ids, a few new quirks, and some small fixes for some regressions that
  have been found after the big 5.2-rc1 merge.

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