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

Pull misc SCSI updates from James Bottomley:
 "This is an assorted set of stragglers into the merge window with
  driver updates for megaraid_sas, lpfc, bfi and mvumi.  It also
  includes some fairly major fixes for virtio-scsi (scatterlist init),
  scsi_debug (off by one error), storvsc (use after free) and qla2xxx
  (potential deadlock).

  Signed-off-by: James Bottomley <JBottomley@Parallels.com>"
