SCSI misc on 20240514

Updates to the usual drivers (ufs, lpfc, qla2xxx, mpi3mr, libsas).
 The major update (which causes a conflict with block, see below) is
 Christoph removing the queue limits and their associated block
 helpers.  The remaining patches are assorted minor fixes and
 deprecated function updates plus a bit of constification.

=============
There is a SCSI documentation directory within the kernel source tree,
typically Documentation/scsi . Most documents are in plain
(i.e. ASCII) text. This file is named scsi_mid_low_api.txt and can be
typically Documentation/scsi . Most documents are in reStructuredText
format. This file is named scsi_mid_low_api.rst and can be
found in that directory. A more recent copy of this document may be found
at http://web.archive.org/web/20070107183357rn_1/sg.torque.net/scsi/.
Many LLDs are documented there (e.g. aic7xxx.txt). The SCSI mid-level is
briefly described in scsi.txt which contains a url to a document
describing the SCSI subsystem in the lk 2.4 series. Two upper level
drivers have documents in that directory: st.txt (SCSI tape driver) and
scsi-generic.txt (for the sg driver).
