ALSA: hda/ca0132: Set HP/Speaker auto-detect default from headphone pin verb

2026-02-28T08:24:21Z

HP/Speaker auto-detect (VNID_HP_ASEL) has been off by default for every CA0132 device since the driver was added in 2012. vnode_lswitch is always initialized to 0 in ca0132_init_chip(), and no quirk or other code path enables it. As a result, headphone jack detection works only after the user manually turns on "HP/Speaker Auto Detect" in alsamixer, which is not obvious on laptops with combo jacks (e.g. Google Link, Alienware). Change the default to follow the headphone pin config: if the pin verb has presence detect enabled (no AC_DEFCFG_MISC_NO_PRESENCE) and the codec supports it (AC_PINCAP_PRES_DETECT), enable HP_ASEL by default. This lets firmware (coreboot, UEFI, etc.) express whether the headphone jack supports insertion detection. Devices with combo jacks can default to auto-detect; devices with fixed/no jack leave it off.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00Z

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

2026-02-21T09:02:28Z

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/ca0132: Use guard() for mutex locks

ALSA: hda/ca0132: Use cleanup macros for PM controls

ALSA: hda/ca0132: Fix missing error handling in ca0132_alt_select_out()

There are a couple of cases where the error is ignored or the error code isn't propagated in ca0132_alt_select_out(). Fix those.

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.
