Merge tag 'usb-5.0-rc2' 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 and quirk updates for 5.0-rc2.

  The majority here are some quirks for some storage devices to get them
  to work properly. There's also a fix here to resolve the reported
  issues with some audio devices that say they are UAC3 compliant, but
  really are not.

  And a fix up for the MAINTAINERS file to remove a dead url.

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