[GIT PULL] SCSI fixes for 6.8-rc6

[GIT PULL] SCSI fixes for 6.8-rc6

[James Bottomley]

Two small fixes, all in drivers (the more obsolete mpt3sas and the
newer mpi3mr).

The patch is available here:

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

The short changelog is:

Arnd Bergmann (1):
      scsi: mpi3mr: Reduce stack usage in mpi3mr_refresh_sas_ports()

Ranjan Kumar (1):
      scsi: mpt3sas: Prevent sending diag_reset when the controller is ready

And the diffstat:

 drivers/scsi/mpi3mr/mpi3mr_transport.c | 7 ++++++-
 drivers/scsi/mpt3sas/mpt3sas_base.c    | 4 +++-
 2 files changed, 9 insertions(+), 2 deletions(-)
