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