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

ALSA: hda/cs8409: Add quirk for CDB35L56-FOUR-HD

2026-01-13T12:25:06Z

Adds quirkiness for the Cirrus Logic CDB35L56-FOUR-HD board. The quirk must be forced by model name "CDB35L56-FOUR-HD" because there isn't a unique SSID that can be used. For example in /etc/modprobe.d: options snd-hda-intel model="CDB35L56-FOUR-HD" The CDB35L56-FOUR-HD is not a complete PC. It is an add-on audio board that requires a host system and replaces the normal HDA codec on the host. Because of this there isn't an SSID that uniquely identifies this configuration. Also, the usual host board is an Aaeon UpXtreme, which doesn't have a unique SSID. Because of this, the quirk must be forced by a module param. This is acceptable because it is a development board, not an end-user system, so there is no need for it to be detected automatically.

ALSA: hda/cirrus: Restrict prompt only for CONFIG_EXPERT

2025-08-07T06:20:59Z

The split of Cirrus HD-audio codec driver may confuse users when migrating from the previous kernel configs and leave the needed drivers disabled. Although we've already set y as default, it's still safer to paper over the wrong choices. This patch marks the prompt of split CS420x and CS421x codec drivers with CONFIG_EXPERT, so that they are all enabled when the top-level CONFIG_SND_HDA_CODEC_CIRRUS is set. For users who really care about the minimalistic configuration, they can turn each driver on/off individually after setting CONFIG_EXPERT=y. This patch adds the missing help text to the top-level CONFIG_SND_HDA_CIRRUS_CODEC together with the explanation of individual choices, and corrects the help texts that don't fit well nowadays, too.

ALSA: hda/cirrus: Enable drivers as default

2025-07-30T13:39:42Z

Like HD-audio Realtek drivers, Cirrus Logic HD-audio codec driver was split to multiple drivers, too, and now users are forced to choose the right kconfig items. For smoother upgrade path, keep the previous CONFIG_SND_HDA_CODEC_CIRRUS as the menuconfig. The new kconfig CONFIG_SND_HDA_CODEC_CS42* are enabled as default, as long as CONFIG_SND_HDA_CODEC_CIRRUS is set, so that the system with Cirrus codec can keep working. This is only about the default config, and each driver can be still disabled if user wants to reduce the size, too.

ALSA: hda/cs8409: Rewrite to new probe method

2025-07-11T07:55:38Z

Convert the CS8409 codec driver to use the new hda_codec_ops probe. The Dolphin support needs an override of unsol_event callback, and redirect via spec->unsol_event function pointer for now. Other than that, no functional changes. Reviewed-by: Richard Fitzgerald Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250709160434.1859-17-tiwai@suse.de

ALSA: hda/cirrus: Split to cs420x and cs421x drivers

2025-07-11T07:55:38Z

Since the codec ops for CS420x and CS421x are fairly independent, split the cirrus codec driver into two drivers, snd-hda-codec-cs420x and snd-hda-code-cs421x. Together with the split, convert to the new hda_codec_ops probe. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250709160434.1859-16-tiwai@suse.de

ALSA: hda: Move codec drivers into sound/hda/codecs directory

2025-07-11T07:55:37Z

Now move the all remaining codec drivers from sound/pci/hda to sound/hda/codecs subdirectory. Some drivers are put under the further vendor subdirectory, and the vendor helper code (*_helper.c) are put under helpers subdirectory. Also the sub-codec drivers are moved under a different subdirectory, sound/hda/codecs/sub-codecs, for distinguishing from the main HD-audio codec drivers. The prefix patch_ and hda_ as well as the suffix _helper are dropped from file names as they are mostly superfluous. No functional changes but just file path shuffling.
