M004: 'snd-hda-codec-cmedia-y' assigned with ':=' but was already
assigned at line 5; previous value is overwritten
sound/hda/codecs/Makefile contains duplicate entries for the C-Media
codec driver — both the composite module definition and the obj-* build
target appear twice:
Line 5: snd-hda-codec-cmedia-y := cmedia.o
Line 10: snd-hda-codec-cmedia-y := cmedia.o (duplicate)
Line 24: obj-$(CONFIG_SND_HDA_CODEC_CMEDIA) += snd-hda-codec-cmedia.o
Line 29: obj-$(CONFIG_SND_HDA_CODEC_CMEDIA) += snd-hda-codec-cmedia.o (duplicate)
This file was created by commit 6014e9021b ("ALSA: hda: Move codec
drivers into sound/hda/codecs directory") which
moved codec drivers from sound/pci/hda/ to sound/hda/codecs/. In that
initial file, cmedia appeared once in each section.
Immediately after, commit aeeb85f26c ("ALSA: hda: Split Realtek
HD-audio codec driver") reordered the entries and
inserted cmedia at new positions near the top of each section, as part
of splitting out the Realtek driver. However, the original cmedia entries
were not removed during this reordering, creating duplicates of both
lines. The second assignment harmlessly overwrites the first with the
same value, and the second obj-* line causes the module to be listed
twice — neither causes a build failure, but both are dead code.
Remove the duplicate entries (second occurrence of each).

The mic-mute LED on the Acer Aspire A315-44P (subsystem ID 0x10251640)
does not light up when the microphone is muted. The LED is connected to
GPIO3 of the Realtek ALC256 codec.
Add a quirk entry using ALC256_FIXUP_ACER_SFG16_MICMUTE_LED, which
configures GPIO3 (bitmask 0x04) as the micmute LED, identical to
the Acer Swift SFG16.
Tested by manually sending HDA verb commands directly to the codec
and verifying that GPIO3 drives the LED while GPIO1 and GPIO2
do not.

The arch_local_irq_*() wrappers in <asm/irqflags.h> dispatch between two
underlying primitives: the __daif_* path on most systems, and the
__pmr_* path on builds that use GIC PMR-based masking (Pseudo-NMI). The
leaf primitives are already __always_inline, but the wrappers themselves
are plain "static inline".
That is unsafe for noinstr callers: nothing prevents the compiler from
emitting an out-of-line copy of e.g. arch_local_irq_disable(), and an
out-of-line copy can be instrumented (ftrace, kcov, sanitizers), which
breaks the noinstr contract on the entry/idle paths that rely on these
helpers.
x86 hit and fixed exactly this class of bug in commit 7a745be1cc
("x86/entry: __always_inline irqflags for noinstr").
Force-inline all of the arch_local_irq_*() wrappers so they cannot be
emitted out-of-line:
- arch_local_irq_enable()
- arch_local_irq_disable()
- arch_local_save_flags()
- arch_irqs_disabled_flags()
- arch_irqs_disabled()
- arch_local_irq_save()
- arch_local_irq_restore()
The primary motivation is noinstr safety. There is a useful side effect
for fleet-wide profiling: when the wrapper is emitted out-of-line,
samples taken inside it during the post-WFI IRQ unmask in
default_idle_call() are attributed to arch_local_irq_enable rather than
default_idle_call(), and the FP-unwinder loses default_idle_call() from
the chain.

On ThinkBook 16p systems the platform mute LED is present and
bound to the audio-mute trigger, but it does not react to Master
mute changes.
The affected fixup chain sets up the DAC routing, but does not enable
vmaster mute LED handling. Because of that, the generic HDA code does
not mark Master Playback Switch with SNDRV_CTL_ELEM_ACCESS_SPK_LED,
and the audio-mute trigger never receives speaker mute updates.
Add a ThinkBook-specific wrapper around alc287_fixup_bind_dacs() and
enable spec->gen.vmaster_mute_led during PRE_PROBE. This keeps the
existing DAC binding logic unchanged while allowing the normal generic
LED path to drive the mute LED.

The UAC3 cluster descriptor length check in
snd_usb_get_audioformat_uac3()was added to
make sure that the buffer is large enough for
a struct uac3_cluster_header_descriptor before the
returned data is cast and used.
However, the check uses sizeof(cluster), where cluster
is a pointer, not the size of the descriptor header.
This makes the validation depend on the architecture
pointer size and does not match the intended object size.
Check against sizeof(*cluster) instead.

loopback_check_format() may stop the capture side when playback starts
with parameters that no longer match a running capture stream. Commit
826af7fa62 ("ALSA: aloop: Fix racy access at PCM trigger") moved
the peer lookup under cable->lock, but the actual snd_pcm_stop() still
runs after dropping that lock.
A concurrent close can clear the capture entry from cable->streams[] and
detach or free its runtime while the playback trigger path still holds a
stale peer substream pointer.
Keep a per-cable count of in-flight peer stops before dropping
cable->lock, and make free_cable() wait for those stops before
detaching the runtime. This preserves the existing behavior while
making the peer runtime lifetime explicit.

Currently the runtime.oss.trigger field may be accessed concurrently
without protection, which may lead to the data race. And, in this
case, it may lead to more severe problem because it's a bit field; as
writing the data, it may overwrite other bit fields as well, which
confuses the operation completely, as spotted by fuzzing.
Fix it by covering runtime.oss.trigger bit fled also with the existing
params_lock mutex in both snd_pcm_oss_get_trigger() and
snd_pcm_oss_poll().

drm_gem_fb_init_with_funcs() computes sub-sampled plane dimensions
using plain integer division:
unsigned int width = mode_cmd->width / (i ? info->hsub : 1);
unsigned int height = mode_cmd->height / (i ? info->vsub : 1);
However, the ioctl-level framebuffer_check() in drm_framebuffer.c uses
drm_format_info_plane_width/height() which round up dimensions via
DIV_ROUND_UP(). This inconsistency corrupts the subsequent GEM object
size check for certain pixel format and dimension combinations.
For example, with NV12 (vsub=2) and a 1-pixel-tall framebuffer the
GEM size validation path sees height=0 instead of height=1. The
expression (height - 1) then wraps to UINT_MAX as an unsigned int,
causing min_size to overflow and wrap back to a small value. A tiny
GEM object therefore passes the size guard, yet when the GPU accesses
the chroma plane it will read or write memory beyond the object's
bounds.
Fix by replacing the open-coded divisions with drm_format_info_plane_width()
and drm_format_info_plane_height(), which use DIV_ROUND_UP() and match
the calculation already used in framebuffer_check().

When enabling ES8390 via ACPI description, es8389 would fail to
obtain a clock source, causing the driver to fail to initialize.
This was not an issue with older kernels, but since commit
abae8e57e4 ("clk: generalize devm_clk_get() a bit"),
devm_clk_get() would return an error pointer when a clock source
was not detected (instead of falling back to a static clock),
causing the driver to fail early.
Use devm_clk_get_optional() instead to return to the previous
behaviour, allowing the use of a static clock source.

kconfiglint reports two warnings for sound/soc/tegra/Makefile:
M002: composite module 'snd-soc-tegra-utils' defined but not in any obj-*
M008: composite module 'snd-soc-tegra-utils': tegra_asoc_utils.o has no
source file
The composite module definition
`snd-soc-tegra-utils-y += tegra_asoc_utils.o` references a source file that
no longer exists and defines a module that is never included in any obj-*
target.
The tegra_asoc_utils module was originally introduced in commit
a3cd50deef ("ASoC: Tegra: Move utilities to separate module") by Stephen
Warren in 2011 to provide shared clock/rate utility functions for Tegra
machine drivers. At that time, the Makefile had both the composite
definition (`snd-soc-tegra-utils-objs`) and the build target
(`obj-$(CONFIG_SND_TEGRA_SOC) += snd-soc-tegra-utils.o`).
In 2021,
commit 8c1b3b1593 ("ASoC: tegra: Squash utils into common machine
driver")
by Dmitry Osipenko merged tegra_asoc_utils.c into tegra_asoc_machine.c,
deleting both the .c and .h files. That commit correctly removed the obj-*
build target line but overlooked the composite module definition line
(`snd-soc-tegra-utils-objs += tegra_asoc_utils.o`).
The orphaned line persisted unnoticed and was even mechanically updated in
2024 by
commit 51a50d6ad7 ("ASoC: tegra: Use *-y instead of *-objs in
Makefile")
by Takashi Iwai, which converted it from `-objs` to `-y` syntax as part of
a treewide cleanup — inadvertently refreshing a stale definition.
Remove the orphaned composite module definition since it serves no purpose:
the source file was deleted, the obj-* target was already removed, and the
functionality now lives in tegra_asoc_machine.c.

The order of operations to derive the temperature from the temp
register values was wrong, since 1000 / 16 is not an integer. This
resulted in the calculated temperature value deviating from the
value represented by the registers slightly, which was most obvious
when the registers were zeroed (-92.265 *C vs the expected -93.000 *C).
Scale the reading before dividing the whole thing by 16 to correct
this.

Two CTRLR0 macros are defined but never referenced, and both are wrong:
- CR0_XFM_MASK shifts by SPI_XFM_OFFSET, which does not exist anywhere
in the tree. The intended symbol is CR0_XFM_OFFSET.
- CR0_MTM_OFFSET is defined as 0x21, i.e. bit 33 of a 32-bit register.
The value is meaningless and the macro is unused.
Drop both. They can be re-introduced correctly when an actual user
appears.

rockchip_spi_isr() decides whether the current interrupt was the
cs-inactive event by reading IMR:
if (rs->cs_inactive &&
readl_relaxed(rs->regs + ROCKCHIP_SPI_IMR) & INT_CS_INACTIVE)
ctlr->target_abort(ctlr);
IMR is the interrupt mask register: it tells which sources are enabled,
not which one fired. In the PIO path, rockchip_spi_prepare_irq() enables
both INT_RF_FULL and INT_CS_INACTIVE in IMR when rs->cs_inactive is true:
if (rs->cs_inactive)
writel_relaxed(INT_RF_FULL | INT_CS_INACTIVE,
rs->regs + ROCKCHIP_SPI_IMR);
so the IMR check is always true once cs_inactive is enabled, and every
PIO interrupt - including normal RF_FULL completions - is dispatched to
ctlr->target_abort(), aborting the transfer. The bug is reachable on
ROCKCHIP_SPI_VER2_TYPE2 in target mode with a DMA-capable controller
when the transfer is short enough to fall back to PIO
(rockchip_spi_can_dma() returns false below fifo_len).
Read ISR (which is RISR masked by IMR) so the check actually reflects
which interrupt fired, and parenthesise the expression for clarity while
at it.

Commit 671dd2ffbd ("ASoC: amd: acp: Add new cpu dai and dailink creation for I2S BT instance")
introduced a change that "broke" Steam Deck's audio probe, in the OLED
model, as observed in the following dmesg snippet:
[...]
snd_sof_amd_vangogh 0000:04:00.5: Topology: ABI 3:26:0 Kernel ABI 3:23:1

sof_mach nau8821-max: error -EINVAL: Failed to register card(sof-nau8821-max)
sof_mach nau8821-max: probe with driver sof_mach failed with error -22
[...]
Notice the quotes in "broke": it's not really a bug in such commit,
but instead a problem with a topology file from Steam Deck OLED. This
was discussed to great extent in [1], and Cristian proposed a pretty
simple and functional change that resolved the issue for the Deck's
issue. That change, though, would break other devices, so it wasn't
accepted upstream. And the proper suggested solution (fix the topology)
was never implemented, so Valve's kernel (and anyone that wants to boot
the mainline on Steam Deck OLED) is carrying that fix downstream.
So, we propose hereby a different approach: a DMI quirk, as many already
present in the sound drivers, to address this issue solely on Steam Deck
OLED, not breaking other devices and as a bonus, allowing simple patch
up in case eventually the topology file gets fixed (we'd just need to
check against any DMI info reflecting that or the topology/FW versions).
The motivation of such upstream quirk is related to users that want
to test latest kernel trees on their devices and get no only non-working
sound device, but seems some games (like Ori and the Blind Forest)
can't properly work without a proper functional audio device.
Example of such report can be seen at [2].

rzv2h_rspi_setup_clock() is declared to return u32 but returns -EINVAL
when no valid clock parameters are found. Cast to u32, -EINVAL becomes
0xffffffea, which is a non-zero value. The caller in
rzv2h_rspi_prepare_message() guards against failure with:
rspi->freq = rzv2h_rspi_setup_clock(rspi, speed_hz);
if (!rspi->freq)
return -EINVAL;
Because 0xffffffea is non-zero, the check is bypassed and the controller
proceeds to program SPBR/SPCMD with stale values, leading to an unknown
bit rate.
Return 0 on the failed-search path, consistent with the existing
clk_set_rate() failure path which already returns 0.

x86_energy_perf_policy accesses the SoC Slider via standard
user/kernel APIs to the processor_thermal_soc_slider driver.
Machines that support SoC Slider largely use it instead of EPP,
which may continue to exist in a diminished role, or vanish entirely.
