This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

The placement of the `segdist_codes` array documentation was corrected
to conform with kernel documentation guidelines. The `@segdist_codes`
was placed incorrectly within the struct `segdist_code` documentation
block, which led to a potential misinterpretation of the code structure.
The `segdist_codes` array documentation was moved outside the struct
block, and a separate comment block was provided for it. This change
ensures that clarity and proper alignment with kernel documentation
standards are maintained.
A kernel-doc warning was addressed:

The kerneldoc comments in drivers/slimbus/stream.c were not properly
formatted, leading to a distinctly unsatisfying "no structured comments
found" warning in the docs build. Sprinkle some asterisks around so that
the comments will be properly recognized.

This patch adds support to SLIMbus stream apis for slimbus device.
SLIMbus streaming involves adding support to Data Channel Management and
channel Reconfiguration Messages to slim core plus few stream apis.
>From slim device side the apis are very simple mostly inline with other
stream apis.
Currently it only supports Isochronous and Push/Pull transport protocols,
which are sufficient for audio use cases.
