ASoC: simple-card-utils: fix graph_util_is_ports0() for DT overlays

2026-03-10T01:02:43Z

graph_util_is_ports0() identifies DPCM front-end (ports@0) vs back-end (ports@1) by calling of_get_child_by_name() to find the first "ports" child and comparing pointers. This relies on child iteration order matching DTS source order. When the DPCM topology comes from a DT overlay, __of_attach_node() inserts new children at the head of the sibling list, reversing the order. of_get_child_by_name() then returns ports@1 instead of ports@0, causing all front-end links to be classified as back-ends. The card registers with no PCM devices. Fix this by matching the unit address directly from the node name instead of relying on sibling order.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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: simple-card-utils: Check device node before overwrite direction

2026-01-05T13:14:44Z

Even the device node don't exist, the graph_util_parse_link_direction() will overwrite the playback_only and capture_only to be zero. Which cause the playback_only and capture_only are not correct, so check device node exist or not before update the value.

ASoC: test-component: Use kcalloc() instead of kzalloc()

Use devm_kcalloc() in test_driver_probe() to gain built-in overflow protection, making memory allocation safer when calculating allocation size compared to explicit multiplication.

2025-06-24T00:01:36Z

Current Kconfig menu at [ALSA for SoC audio support] has no rules. So, some venders are using menu style, some venders are listed each drivers on top page, etc. It is difficult to find target vender and/or drivers because it is very random.

AsoC: Phase out hybrid PCI devres

2025-05-05T23:42:25Z

Merge series from Philipp Stanner : A year ago we spent quite some work trying to get PCI into better shape. Some pci_ functions can be sometimes managed with devres, which is obviously bad. We want to provide an obvious API, where pci_ functions are never, and pcim_ functions are always managed. Thus, everyone enabling his device with pcim_enable_device() must be ported to pcim_ functions. Porting all users will later enable us to significantly simplify parts of the PCI subsystem. See here [1] for details. This patch series does that for sound. Feel free to squash the commits as you see fit. P. [1] https://elixir.bootlin.com/linux/v6.14-rc4/source/drivers/pci/devres.c#L18

ASoC: simple-card-utils: Fix pointer check in graph_util_parse_link_direction

2025-04-30T23:22:35Z

Actually check if the passed pointers are valid, before writing to them. This also fixes a USBAN warning: UBSAN: invalid-load in ../sound/soc/fsl/imx-card.c:687:25 load of value 255 is not a valid value for type '_Bool' This is because playback_only is uninitialized and is not written to, as the playback-only property is absent.

ASoC: simple-card-utils: fixup dlc->xxx handling for error case

2025-04-14T10:48:36Z

Current graph_util_parse_dai() has 2 issue for dlc->xxx handling. 1) dlc->xxx might be filled if snd_soc_get_dai_via_args() (A) works. In such case it will fill dlc->xxx first (B), and detect error after that (C). We need to fill dlc->xxx in success case only. (A) dai = snd_soc_get_dai_via_args(&args); if (dai) { ret = -ENOMEM; ^ dlc->of_node = ... (B) dlc->dai_name = ... v dlc->dai_args = ... (C) if (!dlc->dai_args) goto end; ... } 2) graph_util_parse_dai() itself has 2 patterns (X)(Y) to fill dlc->xxx. Both case, we need to call of_node_put(node) (Z) in error case, but we are calling it only in (Y) case. int graph_util_parse_dai(...) { ... dai = snd_soc_get_dai_via_args(&args); if (dai) { ... ^ dlc->of_node = ... (X) dlc->dai_name = ... v dlc->dai_args = ... ... } ... (Y) ret = snd_soc_get_dlc(&args, dlc); if (ret < 0) { (Z) of_node_put(node); ... } ... } This patch fixup both case.
