Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (target, ufs, smartpqi, lpfc).

  There are some core changes, mostly around reworking some of our user
  context assumptions in device put and moving some code around.

  The remaining updates are bug fixes and minor changes"
