Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This patch consists of the usual driver updates (qla2xxx, qla4xxx,
lpfc, be2iscsi, fnic, ufs, NCR5380) The NCR5380 is the addition to
maintained status of a long neglected driver for older hardware. In
addition there are a lot of minor fixes and cleanups and some more
updates to make scsi mq ready"
