Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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 *". Signed-off-by: Kees Cook

ASoC: Fix acronym for Intel Gemini Lake

2025-12-15T14:08:47+00:00

While the used GML is consistent with the pattern for other Intel * Lake SoCs, the de facto use is GLK. Update the acronym and users accordingly. Note, a handful of the drivers for Gemini Lake in the Linux kernel use GLK already (LPC, MEI, pin control, SDHCI, ...) and even some in ASoC. The only ones in this patch used the inconsistent one.

ALSA: hda: intel-dsp-config: Prefer legacy driver as fallback

2025-12-10T16:23:33+00:00

When config table entries don't match with the device to be probed, currently we fall back to SND_INTEL_DSP_DRIVER_ANY, which means to allow any drivers to bind with it. This was set so with the assumption (or hope) that all controller drivers should cover the devices generally, but in practice, this caused a problem as reported recently. Namely, when a specific kconfig for SOF isn't set for the modern Intel chips like Alderlake, a wrong driver (AVS) got probed and failed. This is because we have entries like: #if IS_ENABLED(CONFIG_SND_SOC_SOF_ALDERLAKE) /* Alder Lake / Raptor Lake */ { .flags = FLAG_SOF | FLAG_SOF_ONLY_IF_DMIC_OR_SOUNDWIRE, .device = PCI_DEVICE_ID_INTEL_HDA_ADL_S, }, .... #endif so this entry is effective only when CONFIG_SND_SOC_SOF_ALDERLAKE is set. If not set, there is no matching entry, hence it returns SND_INTEL_DSP_DRIVER_ANY as fallback. OTOH, if the kconfig is set, it explicitly falls back to SND_INTEL_DSP_DRIVER_LEGACY when no DMIC or SoundWire is found -- that was the working scenario. That being said, the current setup may be broken for modern Intel chips that are supposed to work with either SOF or legacy driver when the corresponding kconfig were missing. For addressing the problem above, this patch changes the fallback driver to the legacy driver, i.e. return SND_INTEL_DSP_DRIVER_LEGACY type as much as possible. When CONFIG_SND_HDA_INTEL is also disabled, the fallback is set to SND_INTEL_DSP_DRIVER_ANY type, just to be sure.
