[PULL 16/16] hw/audio/virtio-snd: Remove unused assignment

Posted by Philippe Mathieu-Daudé 1 year, 10 months ago

Coverity reported:

  >>>     CID 1542933:  Code maintainability issues  (UNUSED_VALUE)
  >>>     CID 1542934:  Code maintainability issues  (UNUSED_VALUE)
  >>>     Assigning value "NULL" to "stream" here, but that stored
          value is overwritten before it can be used.

Simply remove the unused assignments.
