Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This pull includes driver updates from the usual suspects (stex, hpsa,
ncr5380, scsi_dh, qla2xxx, be2iscsi, hisi_sas, cxlflash, aacraid,
mp3sas, megaraid_sas, ibmvscsi, ufs) plus an assortment of
miscellaneous fixes.
The major user visible change of this pull is that we've moved from
monotonically increasing host number to an ida allocated one (meaning
the numbers get re-used) because someone managed to wrap the count in
an iscsi system. We don't believe there will be any adverse
consequences of this"
