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
