Subject: [GIT PULL] SCSI fixes for 6.12-rc2

four small fixes, three in drivers and one in the FC transport class to
add idempotence to state setting.

The patch is available here:

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

The short changelog is:

Avri Altman (1):
      scsi: ufs: Use pre-calculated offsets in ufshcd_init_lrb()

Benjamin Marzinski (1):
      scsi: scsi_transport_fc: Allow setting rport state to current state

Daniel Palmer (1):
      scsi: wd33c93: Don't use stale scsi_pointer value

Martin Wilck (1):
      scsi: fnic: Move flush_work initialization out of if block
