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

Pull SCSI fixes from James Bottomley:
 "Four fixes: one to try to fix our repeated intermittent crashes in
  suspend/resume, one to correct a regression in the optimal I/O size
  reporting and a couple for randconfig build failures in the hisi_sas
  driver"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  SCSI: fix crashes in sd and sr runtime PM
  sd: Optimal I/O size is in bytes, not sectors
  hisi_sas: Restrict SCSI_HISI_SAS to arm64
  hisi_sas: SCSI_HISI_SAS should depend on HAS_DMA
