<div class='commit-subject'>Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi</div><div class='commit-msg'>Pull late SCSI updates from James Bottomley:
 "This is mostly stuff which missed the initial pull.

  There's a new driver: qedi, and some ufs, ibmvscsis and ncr5380
  updates plus some assorted driver fixes and also a fix for the bug
  where if a device goes into a blocked state between configuration and
  sysfs device add (which can be a long time under async probing) it
  would become permanently blocked"
