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

Pull SCSI fixes from James Bottomley:
 "Six fixes, all of which appear to have user visible consequences.

  The DMA one is a regression fix from the merge window and of the
  others, four are driver specific and one specific to the target code"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: ufs: Use explicit access size in ufshcd_dump_regs
  scsi: tcmu: fix use after free
  scsi: csiostor: fix NULL pointer dereference in csio_vport_set_state()
  scsi: lpfc: nvmet: avoid hang / use-after-free when destroying targetport
  scsi: lpfc: nvme: avoid hang / use-after-free when destroying localport
  scsi: communicate max segment size to the DMA mapping code
