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
