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

Pull SCSI fixes from James Bottomley:
 "This is the first sweep of mostly minor fixes. There's one security
  one: the read past the end of a buffer in qedf, and a panic fix for
  lpfc SLI-3 adapters, but the rest are a set of include and build
  dependency tidy ups and assorted other small fixes and updates"

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