  EDD: enable symlinks to SCSI devices
  
  Symlinks from /sys/firmware/edd/int13_dev8x/disc to the appropriate
  SCSI discs were added a year ago, but disabled because the
  scsi_bus list contained non-'scsi_device's at that time, which
  could have lead to an improper pointer following.    The SCSI
  mid-layer has rectified this, so this code can be re-enabled
  in edd.c once again.
