    sound: Make device cloning work
    
    * Some lockstatus() calls were wrong and needed to be compared
      with LK_EXCLUSIVE
    
    * The sound device caches dynamically created devices and tries
      to reuse them, but devfs got angry if the clone code passed
      it a device which was already in the filesystem namespace. devfs
      had to be modified in 2c94b9eeb85c6cfa5ff918aa58ce484b27fc7c91
      and eb1c7cbc9e1052820efc6b0b7a94c40a7d45b329
    
    * The clone code was designed to clone to new unit numbers, not
      clone an existing unit into multiple channels
