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.

snd_ctl_new1() can return NULL when memory allocation fails.
snd_gf1_pcm_volume_control() does not check the return value before
dereferencing kctl->id.index, which can lead to a NULL pointer
dereference.
Add a NULL check after snd_ctl_new1() and return -ENOMEM if it fails.

The InterWave PM patch added snd_interwave_restore_regs() and
snd_interwave_restore_memory() as static helpers, but both are used only
from the resume path under CONFIG_PM.
On configurations without CONFIG_PM, such as alpha allyesconfig, this
leaves both helpers unused and triggers -Wunused-function warnings with
W=1.
Move the PM-only helpers into the existing CONFIG_PM section. Keep
__snd_interwave_restore_regs() outside the guard because it is also used
during probe-time initialization.

interwave still leaves both its ISA and PnP PM callbacks disabled even
though the shared GUS suspend and resume path now exists.
This board needs InterWave-specific glue around the shared GUS PM path.
The attached WSS codec has its own register image that must be saved and
restored across suspend, the InterWave-specific GF1 compatibility,
decode, MPU401, and emulation settings must be rewritten after the
shared GF1 resume path reinitializes the chip, and the probe-detected
InterWave memory layout must be restored without rerunning the
destructive DRAM/ROM detection path.
Track the optional STB TEA6330T bus at probe time, restore its cached
mixer state after resume, add resume-safe helpers for the InterWave
register and memory-configuration state, and wire both the ISA and PnP
front-ends up to the shared GUS PM helpers.
The resume path intentionally restores only the cached hardware setup.
It does not attempt to preserve sample RAM contents across suspend.

gusmax still leaves its ISA PM callbacks disabled even though the shared
GF1 suspend and resume path now exists.
This board needs one extra piece of PM glue around the shared GF1 helpers.
The attached WSS codec has its own register image that must be saved and
restored across suspend, and the MAX control register must be rewritten on
resume before the codec and GF1 sides are brought back.
Use the existing wss->suspend() and wss->resume() hooks for the codec, then
wire the driver up to the shared GUS suspend and resume helpers for the GF1
side.

gusextreme still leaves its ISA PM callbacks disabled because the shared
GF1 core had no suspend and resume path suitable for PM recovery.
Resume on this board needs one extra step before the shared GF1 path can
touch the chip again: the ES1688 side must restore the GF1 routing. Split
that routing sequence into a helper, reuse it for probe and resume, reset
the ES1688 side first on resume, and then wire the driver up to the shared
GUS PM helpers.
This restores usable post-resume GF1 operation on GUS Extreme without
rerunning probe-only detection in the shared GF1 path.

gusclassic and gusextreme still leave their ISA PM callbacks disabled
because the shared GF1 core only provides probe-time startup and full
shutdown paths.
Those helpers are not suitable for suspend and resume. They reset software
handlers and tear down runtime state such as the DRAM allocator, timer
state, DMA queues, PCM state and UART setup. Resume instead needs a
narrower recovery path that rebuilds the GF1 hardware state without
rerunning probe-only detection or discarding the bookkeeping kept by the
card instance.
Add shared GF1 suspend and resume helpers for that recovery path. Suspend
now quiesces GF1 PCM, aborts queued GF1 DMA work, resets the UART and
powers the chip down without tearing down allocator, timer or rawmidi
bookkeeping. Resume rebuilds the GF1 hardware state, restores timer and
UART handlers, and brings the chip back to a usable post-resume state for
the ISA front-ends.
The scope is limited to restoring post-resume usability. It does not
attempt transparent continuation of active GF1 PCM or synth state across
suspend, and userspace may still need to reprepare streams or reload
onboard sample data after resume. Open rawmidi substreams are restored
only to a usable post-resume state.

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 *".

Upon review, this commit was found to be incorrect for the reasons

The original commit did nothing if there was an error, except to print

Pointers should be printed with %p or %px rather than
cast to long type and printed with %lx.
Drop the address printing.

Simplify the proc fs creation code with new helper functions,
snd_card_ro_proc_new() and snd_card_rw_proc_new().
Just a code refactoring and no functional changes.

We used to pass NULL to memory allocators for ISA devices due to
historical reasons. But we prefer rather a proper device object to be
assigned, so let's fix it by replacing snd_dma_isa_data() call with
card->dev reference, and kill snd_dma_isa_data() definition.
