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"
