Replace manual ioremap() calls with pcim_iomap() which uses devres
for automatic cleanup. This eliminates the need for manual iounmap()
in both the error path of asihpi_adapter_probe() and the
asihpi_adapter_remove() function.
The pcim_iomap() helper is cleaner and less error-prone since it
handles unmapping automatically when the PCI device is released.

create_adapter_obj() retrieves adapter information by calling
hpi6000_message_response_sequence(). This function reports transport-level
errors through its return value and DSP-reported errors via hr0.error.
The current code only checks hr0.error, causing transport-level errors to
be ignored. As a result, adapter initialization may continue with an
invalid response.
Check the return value of hpi6000_message_response_sequence() before
examining hr0.error.

... and PCI device helpers.
The various struct pci_device_id arrays were initialized mostly by list
expressions, some of them using the PCI_DEVICE macros. This isn't easily
readable if you're not into PCI. Using named initializers is more
explicit and thus easier to parse. Also use PCI_DEVICE* helper macros to
assign .vendor, .device, .subvendor and .subdevice where appropriate and
skip explicit assignments of 0 (which the compiler takes care of).
The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.
This change doesn't introduce changes to the compiled pci_device_id
array. Tested on x86 and arm64.

asihpi_ctl_init() builds mixer control names in the fixed 44-byte
hpi_ctl->name buffer with sprintf().
This is not only a defensive cleanup. The current in-tree name tables and
format strings can already exceed 44 bytes. For example,
"Bitstream 0 Internal 0 Monitor Playback Volume"
is 46 characters before the trailing NUL, so the current sprintf() call
writes past the end of hpi_ctl->name.
The generated control name is used as the ALSA control element key, so
blindly truncating it is not sufficient. Switch the formatting to
snprintf() and emit an error if truncation happens, showing the
truncated name while still keeping the write bounded to hpi_ctl->name.

clang-22 rightfully warns that the memcpy() in adapter_prepare() copies
between different structures, crossing the boundary of nested
structures inside it:
In file included from sound/pci/asihpi/hpimsgx.c:13:
In file included from include/linux/string.h:386:
include/linux/fortify-string.h:569:4: error: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
569 | __write_overflow_field(p_size_field, size);
The two structures seem to refer to the same layout, despite the
separate definitions, so the code is in fact correct.
Avoid the warning by copying the two inner structures separately.
I see the same pattern happens in other functions in the same file,
so there is a chance that this may come back in the future, but
this instance is the only one that I saw in practice, hitting it
multiple times per day in randconfig build.

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 *".
