ASoC: codecs: ab8500: Fix casting of private data

2026-05-23T11:07:11+00:00

[ Upstream commit a201aef1a88b675e9eb8487e27d14e2eef3cef80 ] ab8500_filter_controls[i].private_value is initialized using .private_value = (unsigned long)&(struct filter_control) {.count = xcount, .min = xmin, .max = xmax} thus it's a pointer to a struct filter_control casted to unsigned long. So to get back that pointer .private_data must be cast back, not its address. Fixes: 679d7abdc754 ("ASoC: codecs: Add AB8500 codec-driver") Signed-off-by: Christian A.

ASoC: tas2770: Fix order of operations for temperature calculation

2026-05-23T11:07:08+00:00

[ Upstream commit c7ecb6a61908c2604dda6e42da66724d256de7b9 ] The order of operations to derive the temperature from the temp register values was wrong, since 1000 / 16 is not an integer. This resulted in the calculated temperature value deviating from the value represented by the registers slightly, which was most obvious when the registers were zeroed (-92.265 *C vs the expected -93.000 *C). Scale the reading before dividing the whole thing by 16 to correct this.

ASoC: amd: acp: Add DMI quirk for Valve Steam Deck OLED

2026-05-23T11:07:07+00:00

[ Upstream commit b0f6f4ac7d5d04fe2adcdd63ed1cd1ad505b8958 ] Commit 671dd2ffbd8b ("ASoC: amd: acp: Add new cpu dai and dailink creation for I2S BT instance") introduced a change that "broke" Steam Deck's audio probe, in the OLED model, as observed in the following dmesg snippet: [...] snd_sof_amd_vangogh 0000:04:00.5: Topology: ABI 3:26:0 Kernel ABI 3:23:1 sof_mach nau8821-max: ASoC: physical link acp-bt-codec (id 2) not exist sof_mach nau8821-max: ASoC: topology: could not load header: -22 snd_sof_amd_vangogh 0000:04:00.5: tplg amd/sof-tplg/sof-vangogh-nau8821-max.tplg component load failed -22 snd_sof_amd_vangogh 0000:04:00.5: error: failed to load DSP topology -22 snd_sof_amd_vangogh 0000:04:00.5: ASoC error (-22): at snd_soc_component_probe() on 0000:04:00.5 sof_mach nau8821-max: ASoC: failed to instantiate card -22 sof_mach nau8821-max: error -EINVAL: Failed to register card(sof-nau8821-max) sof_mach nau8821-max: probe with driver sof_mach failed with error -22 [...] Notice the quotes in "broke": it's not really a bug in such commit, but instead a problem with a topology file from Steam Deck OLED. This was discussed to great extent in [1], and Cristian proposed a pretty simple and functional change that resolved the issue for the Deck's issue. That change, though, would break other devices, so it wasn't accepted upstream. And the proper suggested solution (fix the topology) was never implemented, so Valve's kernel (and anyone that wants to boot the mainline on Steam Deck OLED) is carrying that fix downstream. So, we propose hereby a different approach: a DMI quirk, as many already present in the sound drivers, to address this issue solely on Steam Deck OLED, not breaking other devices and as a bonus, allowing simple patch up in case eventually the topology file gets fixed (we'd just need to check against any DMI info reflecting that or the topology/FW versions). The motivation of such upstream quirk is related to users that want to test latest kernel trees on their devices and get no only non-working sound device, but seems some games (like Ori and the Blind Forest) can't properly work without a proper functional audio device. Example of such report can be seen at [2].

ASoC: SOF: compress: return the configured codec from get_params

2026-05-23T11:06:41+00:00

[ Upstream commit 2c4fdd055f92a2fc8602dcd88bcea08c374b7e8b ] The SOF compressed offload path accepts codec parameters in sof_compr_set_params() and forwards them to firmware as extended data in the SOF IPC stream params message. However, sof_compr_get_params() still returns success without filling the snd_codec structure. Since the compress core allocates that structure zeroed and copies it back to userspace on success, SNDRV_COMPRESS_GET_PARAMS returns an all-zero codec description even after the stream has been configured successfully. The stale TODO in this callback conflates get_params() with capability discovery. Supported codec enumeration belongs in get_caps() and get_codec_caps(). get_params() should report the current codec settings. Cache the codec accepted by sof_compr_set_params() in the per-stream SOF compress state and return it from sof_compr_get_params().

ASoC: rsnd: Fix potential out-of-bounds access of component_dais[]

2026-05-23T11:06:41+00:00

[ Upstream commit f9e437cddf6cf9e603bdaefe148c1f4792aaf39c ] component_dais[RSND_MAX_COMPONENT] is initially zero-initialized and later populated in rsnd_dai_of_node(). However, the existing boundary check: if (i >= RSND_MAX_COMPONENT) does not guarantee that the last valid element remains zero. As a result, the loop can rely on component_dais[RSND_MAX_COMPONENT] being zero, which may lead to an out-of-bounds access. Found by Linux Verification Center (linuxtesting.org) with SVACE.
