Replace the earlier LeapRAID ncq_cmd_prio_enable attribute with the
standard sas_ncq_prio_supported and sas_ncq_prio_enable names documented in
Documentation/ABI/testing/sysfs-block-device, and rename the per-device NCQ
priority state to match.

The earlier ncq_cmd_prio_enable name has not yet been established as part
of a released userspace ABI, so no compatibility alias is needed.

For LeapRAID, sas_ncq_prio_enable is backed by the driver's per-device NCQ
priority state and controls whether RT-class I/O requests are issued with
command priority on supported SATA devices.

Update leapraid.rst to describe the standard attribute names and paths, and
clean up the surrounding RST text for consistency with kernel documentation
style.

Also switch the capability check from open-coded VPD page 0x89 parsing to
sas_ata_ncq_prio_supported(), use kstrtobool() for the enable path, and
expose the NCQ priority attributes only for SATA devices using LeapRAID's
target-private SAS device state.

Pull SCSI updates from James Bottomley:
 "Usual driver updates (qla2xxx, mpi3mr, mpt3sas, ufs) plus assorted
  cleanups and fixes.

  The biggest core change is the massive code motion in the sd driver to
  remove forward declarations and the most significant change is to
  enumify the queuecommand return"

In clang version 21.1 and later the -Wimplicit-enum-enum-cast warning
option has been introduced. This warning is enabled by default and can
be used to catch .queuecommand() implementations that return another
value than 0 or one of the SCSI_MLQUEUE_* constants. Hence this patch
that changes the return type of the .queuecommand() implementations from
'int' into 'enum scsi_qc_status'. No functionality has been changed.

Instances are passed struct block_device *bdev argument; the only thing
it is used for (if it's used in the first place) is bdev->bd_disk.
Might as well pass that in the first place...

Both helpers are reading the partition table of the disk specified
by block_device of some partition on it; result depends only upon
the disk in question, so we might as well pass the struct gendisk
instead.

This patch updates the scsi_fc_transport.rst documentation by replacing
the outdated << To Be Supplied >> placeholder under the "FC Remote Ports
(rports)" section with a detailed explanation of remote port
functionality in the Fibre Channel (FC) transport class.

The new documentation covers:

 - What rports are and their role in FC-based SCSI communication

 - Their representation in sysfs (/sys/class/fc_remote_ports/)

 - Common sysfs attributes such as (port_id, port_name, node_name, and
   port_state).

 - Their typical lifecycle (creation and removal)

 - Guidance for driver developers on using fc_remote_port_add() and
   fc_remote_port_delete()

This change improves the completeness and usefulness of the FC transport
documentation for developers and users interacting with Fibre Channel
drivers in the Linux SCSI subsystem
