This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci
This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.
Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.

The LeapRAID driver provides support for LeapRAID PCIe RAID controllers,
enabling communication between the host operating system, firmware, and
hardware for efficient storage management.
The driver is organized into several logical modules, each with a clear
responsibility:
leapraid_os.c: Integrates with the Linux SCSI subsystem, handling host
template callbacks, PCIe device probing, and initialization.
leapraid_func.c: Contains low-level routines for firmware/hardware
interaction, interrupt handling, and reset logic.
leapraid_app.c: Provides the ioctl interface for user-space tools.
leapraid_transport.c: Manages interactions with the SCSI transport
layer for SAS PHYs and ports.
leapraid_func.h: Contains internal definitions shared among driver
modules.
leapraid.h: Contains low-level hardware definitions for
driver/firmware interaction.
The leapraid_probe() function orchestrates the setup: it allocates the
adapter structure and SCSI host, configures hardware interfaces, and
registers it with the SCSI mid-layer. Following registration,
scsi_scan_host() is invoked to initiate device discovery, with firmware
reporting devices via interrupt-driven events.
This initial commit provides the necessary infrastructure for
subsequent development of full I/O path handling, error recovery,
and advanced management features.
