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the outdated 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

Update scsi_mid_low_api.rst for changes to struct scsi_host and
struct scsi_cmnd.
struct scsi_host:
- no_async_abort is gone
- drop sh_list w/ no replacement
- change my_devices to __devices
struct scsi_cmnd:
- removed 'done' (now in struct scsi_driver); use scsi_done() or
scsi_done_direct() callbacks
- change previous request_bufflen to scsi_bufflen()
- change previous use_sg field to scsi_dma_map() or scsi_sg_count()
- change previous request_buffer field to reference to 'usg_sg' text
[mkp: removed more obsolete stuff]
