Merge tag 'usb-5.19-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB driver fixes from Greg KH:
 "Here are some small USB driver fixes and new device ids for 5.19-rc7.
  They include:

   - new usb-serial driver ids

   - typec uevent fix

   - uvc gadget driver fix

   - dwc3 driver fixes

   - ehci-fsl driver fix

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