The BCM63xx I2S platform driver matches brcm,bcm63xx-i2s using
snd_soc_bcm_audio_match. With SND_BCM63XX_I2S_WHISTLER=m, the platform
bus emits an OF modalias but snd-soc-63xx does not publish that table.
Export the existing OF IDs for module autoloading. The PCM companion
and the probe path remain unchanged.

again.

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 *".

Fix an issue detected by the Smatch tool:
sound/soc/bcm/bcm63xx-pcm-whistler.c:264 i2s_dma_isr()
error: uninitialized symbol 'val_1'.
sound/soc/bcm/bcm63xx-pcm-whistler.c:264 i2s_dma_isr()
error: uninitialized symbol 'val_2'.
These errors were triggered because the variables 'val_1' and 'val_2'
could remain uninitialized if 'offlevel' is zero, meaning the loop
that assigns values to them does not execute. In this case,
'dma_addr_next' would use uninitialized data, potentially leading
to undefined behavior.
To resolve this, a conditional update for 'dma_addr_next' is added,
ensuring it is assigned only when 'val_1' and 'val_2' are read.
A new boolean variable 'val_read' flags when the values have been
retrieved, setting 'dma_addr_next' only if valid data is available.
This solution prevents the use of uninitialized data, maintaining
defined behavior for 'dma_addr_next' in all cases, and aligns with
expected usage of I2S RX descriptor data.

Merge series from Javier Carrasco <javier.carrasco.cruz@gmail.com>:
Declare `snd_soc_component_driver` as const to move their declarations
to read-only sections for the drivers that do not modify the struct
after its declaration.
Apart from a single case under media/, the affected drivers are members
of the ASoC subsystem.
The bcm2835 I2S driver uses a rbtree register cache but has no clear need
to do so. Since the maple tree cache uses a more modern data structure and
makes implementation decisions more suitable for current systems switch the
driver to use that instead. No functional changes.

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove

As diffstat shows, we've had lots of developments in a wide range
at this time; the majority of changes are about ASoC, including
subsystem-wide cleanups, continued SOF / Intel updates and a
bunch of new drivers (as usual), while there have been some
significant (but almost invisible) improvements in ALSA core
side, too. Below are some highlights:
Core:
- Faster lookups of control elements with Xarray; normal user
won't notice, but on the devices with tons of control elements,
it can be visibly faster
- Support for input validation for controls; this will harden
for badly written drivers in general with a slight overhead
- Deferred async signal handling for working around the potential
deadlocks
- Cleanup / refactoring raw MIDI locking code
ASoC:
- Restructing of the set_fmt() callbacks for making things clearer
in situations like CODEC to CODEC links
- Clean up and modernizing the DAI naming scheme setups
- Merge of more of the Intel AVS driver stack, including some
board integrations
- New version 4 mechanism for communication with SOF DSPs
- Suppoort for dynamically selecting the PLL to use at runtime on
i.MX platforms
- Improvements for CODEC to CODEC support in the generic cards
- Support for AMD Jadeite and various machines, AMD RPL, Intel
MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra
MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and
WAS883x, and Texas Instruments TAS2780
HD- and USB-audio:

Instead of manually managing its DMA buffers using
dma_{alloc,free}_coherent() lets the sound core take care of this using
managed buffers.
On one hand this reduces the amount of boiler plate code, but the main
motivation for the change is to use the shared code where possible. This
makes it easier to argue about correctness and that the code does not
contain subtle bugs like data leakage or similar.

The NULL check can be done gracefully without cast. It fixes a
compile warning like:
sound/soc/bcm/bcm63xx-pcm-whistler.c:184:6: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

There is no big difference at implementation for .suspend/.resume
between DAI driver and Component driver.
But because some driver is using DAI version, thus ALSA SoC needs
to keep supporting it, hence, framework becoming verbose.
If we can switch all DAI driver .suspend/.resume to Component driver,
we can remove verbose code from ALSA SoC.
Driver is getting its private data via dai->dev.
But dai->dev and component->dev are same dev, thus, we can convert
these. For same reason, we can convert dai->active to
component->active if necessary.
This patch moves DAI driver .suspend/.resume to Component driver

ASoC PCM core deals the empty ioctl field now as default.
Let's kill the redundant lines.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>
@@
expression ret;
struct platform_device *E;
@@
ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);
if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>
While we're here, remove braces on if statements that only have one
statement (manually).

Use devm_platform_ioremap_resource() to simplify the code a bit.
This is detected by coccinelle.
