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

Pull SCSI fixes from James Bottomley:
 "Three small driver fixes and one larger unused function set removal in
  the raid class (so no external impact)"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: snic: Fix double free in snic_tgt_create()
  scsi: core: raid_class: Remove raid_component_add()
  scsi: ufs: ufs-qcom: Clear qunipro_g4_sel for HW major version > 5
  scsi: ufs: mcq: Fix the search/wrap around logic
