Merge tag 'usb-5.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are a number of USB fixes for 5.7-rc6

  The "largest" in here is a bunch of raw-gadget fixes and api changes
  as the driver just showed up in -rc1 and work has been done to fix up
  some uapi issues found with the original submission, before it shows
  up in a -final release.

  Other than that, a bunch of other small USB gadget fixes, xhci fixes,
  some quirks, andother tiny fixes for reported issues.

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