ASoC: SOF: ipc4-topology: Allow bytes controls without initial payload

2026-03-26T11:16:03+00:00

It is unexpected, but allowed to have no initial payload for a bytes control and the code is prepared to handle this case, but the size check missed this corner case. Update the check for minimal size to allow the initial size to be 0.

ASoC: SOF: topology: reject invalid vendor array size in token parser

2026-03-20T12:52:41+00:00

sof_parse_token_sets() accepts array->size values that can be invalid for a vendor tuple array header. In particular, a zero size does not advance the parser state and can lead to non-progress parsing on malformed topology data. Validate array->size against the minimum header size and reject values smaller than sizeof(*array) before parsing. This preserves behavior for valid topologies and hardens malformed-input handling.

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

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.
