      ALSA: usb-audio: Fix substream assignments · 8260ef07
      Takashi Iwai authored
      In 3.5 kernel, the endpoint is assigned dynamically for the
      substreams, but the PCM assignment still checks the presence of the
      endpoint pointer.  This ended up in duplicated PCM substream creations
      at probing time, resulting in kernel warnings like:

      This patch fixes the regression by checking the fixed endpoint number
      for each substream instead of the endpoint pointer.
