      ALSA: snd_usb_caiaq: track submitted output urbs · da6094ea
      Daniel Mack authored
      The snd_usb_caiaq driver currently assumes that output urbs are serviced
      in time and doesn't track when and whether they are given back by the
      USB core. That usually works fine, but due to temporary limitations of
      the XHCI stack, we faced that urbs were submitted more than once with
      this approach.
      As it's no good practice to fire and forget urbs anyway, this patch
      introduces a proper bit mask to track which requests have been submitted
      and given back.
      That alone however doesn't make the driver work in case the host
      controller is broken and doesn't give back urbs at all, and the output
      stream will stop once all pre-allocated output urbs are consumed. But
      it does prevent crashes of the controller stack in such cases.
      See http://bugzilla.kernel.org/show_bug.cgi?id=40702
       for more details.
