    scsi_cd - don't lock tray on cdcheckmedia()
     * Move the tray locking explicitly to cdopen(), so that it matches the
       unlocking in cdclose().
     * Before disk probing existed this wasn't a problem as every device was
       first opened, then operated on, then closed.
     * The disk probing code operates directly on the device, which caused
       it to be locked via cdcheckmedia() but never unlocked since no
       close() was ever called.
