[GIT PULL] SCSI fixes for 6.5-rc7

[James Bottomley <James.Bottomley@HansenPartnership.com>]

Three small driver fixes and one larger unused function set removal in
the raid class (so no external impact).

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Bao D. Nguyen (1):
      scsi: ufs: mcq: Fix the search/wrap around logic

Neil Armstrong (1):
      scsi: ufs: ufs-qcom: Clear qunipro_g4_sel for HW major version > 5

Zhu Wang (2):
      scsi: snic: Fix double free in snic_tgt_create()
      scsi: core: raid_class: Remove raid_component_add()

And the diffstat:
