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

Pull second SCSI update from James "Jaj B" Bottomley:
 "This is the final round of SCSI patches for the merge window.  It
  consists mostly of driver updates (bnx2fc, ibmfc, fnic, lpfc,
  be2iscsi, pm80xx, qla4x and ipr).

  There's also the power management updates that complete the patches in
  Jens' tree, an iscsi refcounting problem fix from the last pull, some
  dif handling in scsi_debug fixes, a few nice code cleanups and an
  error handling busy bug fix."
