Pull SCSI updates from James Bottomley:
 "This update includes the usual round of major driver updates (ncr5380,
  lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).

  There's also an assortment of minor fixes, mostly in error legs or
  other not very user visible stuff. The major change is the
  pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this
  effectively makes IRQ mapping generic for the drivers and allows
  blk_mq to use the information"
