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

Pull SCSI updates from James Bottomley:
 "This consists of the usual driver updates (ufs, smartpqi, lpfc,
  target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
  fixes.

  Notable core changes are the removal of scsi->tag which caused some
  churn in obsolete drivers and a sweep through all drivers to call
  scsi_done() directly instead of scsi->done() which removes a pointer
  indirection from the hot path and a move to register core sysfs files
  earlier, which means they're available to KOBJ_ADD processing, which
  necessitates switching all drivers to using attribute groups"
