ASoC: SOF: Intel: add an empty adr_link

2026-05-23T11:09:27+00:00

[ Upstream commit 3c6f06a200796ae7b2b1065e8a6499b138e27a50 ] An empty adr_link is expected to terminate the for (adr_link = mach_params->links; adr_link->num_adr; adr_link++) loop. Allocate link_num + 1 links to add an empty adr_link.

ASoC: SOF: Intel: hda: Place check before dereference

2026-05-23T11:08:50+00:00

[ Upstream commit 6cbc8360f51a3df2ea16a786b262b9fe44d4c68c ] The struct hext_stream is dereferenced before it is checked for NULL. Although it can never be NULL due to a check prior to hda_dsp_iccmax_stream_hw_params() being called, this change clears any confusion regarding hext_stream possibly being NULL. Check hext_stream for NULL and then assign its members. Detected by Smatch: sound/soc/sof/intel/hda-stream.c:488 hda_dsp_iccmax_stream_hw_params() warn: variable dereferenced before check 'hext_stream' (see line 486) Fixes: aca961f196e5d ("ASoC: SOF: Intel: hda: Add helper function to program ICCMAX stream") Signed-off-by: Ethan Tidmore Link: https://patch.msgid.link/20260324173830.17563-1-ethantidmore06@gmail.com Signed-off-by: Mark Brown Signed-off-by: Sasha Levin

ASoC: SOF: Intel: hda: modify period size constraints for ACE4

2026-04-08T12:15:40+00:00

Intel ACE4 based products set more strict constraints on HDA BDLE start address and length alignment. Add a constraint to align period size to 128 bytes. The commit removes the "minimum as per HDA spec" comment. This comment was misleading as spec actually does allow a 2 byte BDLE length, and more importantly, period size also directly impacts how the BDLE start addresses are aligned, so it is not sufficient just to consider allowed buffer length.

ASoC: SOF: Intel: fix iteration in is_endpoint_present()

2026-04-06T12:23:32+00:00

is_endpoint_present() iterates over sdca_data.num_functions, but checks the dai_type according to codec info list, which will cause problems if not all endpoints from the codec info list are present. Make sure the type of actually present functions is compared against target dai_type.

ASoC: SOF: Intel: Fix endpoint index if endpoints are missing

2026-04-06T12:23:31+00:00

In case of missing endpoints, the sequential numbering will cause wrong mapping. Instead, assign the original DAI index from codec_info_list.

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. 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

Merge tag 'asoc-v6.20' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2026-02-09T16:39:11+00:00

ASoC: Updates for v7.0 This release is almost all abut driers, there's very little core work here, although some of that driver work is in more generic areas like SDCA and SOF: - Generic SDCA support for reporting jack events. - Continuing platform support, cleanup and feature improements for the AMD, Intel, Qualcomm and SOF code. - Platform description improvements for the Cirrus drivers. - Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo CV1800B. We also pulled in one small SPI API update and some more substantial regmap work (cache description improvements) for use in drivers.
