Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI fix from James Bottomley:
 "One fix for SAS attached SATA CD-ROMs. It turns out that the libata
  handling of CD devices relies on the SCSI error handler, so disable
  async aborts (which don't start the error handler) for these devices"
