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,
ufs, lpfc, be2iscsi, hisi_sas, storvsc, cxlflash, aacraid,
megaraid_sas, ...).
There's also an assortment of minor fixes and the major update of
switching a bunch of drivers to pci_alloc_irq_vectors from Christoph"
