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

Pull SCSI fixes from James Bottomley:
 "Fixes all in drivers. The largest is the mpi3mr which corrects a phy
  count limit that should only apply to the controller but was being
  incorrectly applied to expander phys"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: target: core: Fix null-ptr-deref in target_alloc_device()
  scsi: mpi3mr: Validate SAS port assignments
  scsi: ufs: core: Set SDEV_OFFLINE when UFS is shut down
