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

Pull SCSI fixes from James Bottomley:
 "This is quite a big update because it includes a rework of the lpfc
  driver to separate the NVMe part from the FC part.

  The reason for doing this is because two separate trees (the nvme and
  scsi trees respectively) want to update the individual components and
  this separation will prevent a really nasty cross tree entanglement by
  the time we reach the next merge window.

  The rest of the fixes are the usual minor sort with no significant
  security implications"
