SCSI misc on 20140815 

This is a small set of updates which missed the first pull.  It's more msix
 updates, some iscsi and qla4xxx fixes, we also have some string null
 termination fixes a return value fix and a couple of pm8001 firmware fixes.

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

Pull more SCSI changes from James Bottomley:
 "This is a small set of updates which missed the first pull.  It's more
  msix updates, some iscsi and qla4xxx fixes, we also have some string
  null termination fixes a return value fix and a couple of pm8001
  firmware fixes.

  Just a note, we do have a couple of bug fixes coming under separate
  cover, but they don't have to be part of the merge window"
