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

Pull SCSI fixes from James Bottomley:
 "Three minor fixes: a NULL deref in qedf, an off by one in sg and a fix
  to IPR to prevent an error on initialisation"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: qedf: Fix a potential NULL pointer dereference
  scsi: sg: off by one in sg_ioctl()
  scsi: ipr: Set no_report_opcodes for RAID arrays
