ASoC: SOF: Intel: hda: Fix NULL pointer dereference

2026-03-04T12:20:15+00:00

[ Upstream commit 16c589567a956d46a7c1363af3f64de3d420af20 ] If there's a mismatch between the DAI links in the machine driver and the topology, it is possible that the playback/capture widget is not set, especially in the case of loopback capture for echo reference where we use the dummy DAI link. Return the error when the widget is not set to avoid a null pointer dereference like below when the topology is broken.

ASoC: SOF: Intel: use hdev->info.link_mask directly

2026-02-03T13:47:11+00:00

The link_mask variable is not changed after setting to hdev->info.link_mask until it is used for another purpose to get the used SoundWire links and set to mach->mach_params.links. Besides, the link_mask variable should be reset before any link id is added to the link_mask. To fix the issue above and avoid confusing, use the hdev->info.link_mask variable directly to check if the SoundWire link is enabled.

ASoC: SOF: Intel: pci-mtl: Change the topology path to intel/sof-ipc4-tplg

2025-12-15T14:07:30+00:00

The default topology path for IPC4 is intel/sof-ipc4-tplg with a symlink to it as intel/sof-ace-tplg to support old kernels. sof-bin has been released in this manner for almost two years now, it is time to change the default path for MTL family.

2025-12-02T06:12:56+00:00

ASoC: Updates for v6.19 This is a very large set of updates, as well as some more extensive cleanup work from Morimto-san we've also added a generic SCDA class driver for SoundWire devices enabling us to support many chips with no custom code. There's also a batch of new drivers added for both SoCs and CODECs. - Added a SoundWire SCDA generic class driver, pulling in a little regmap work to support it. - A *lot* of cleaup and API improvement work from Morimoto-san. - Lots of work on the existing Cirrus, Intel, Maxim and Qualcomm drivers. - Support for Allwinner A523, Mediatek MT8189, Qualcomm QCM2290, QRB2210 and SM6115, SpacemiT K1, and TI TAS2568, TAS5802, TAS5806, TAS5815, TAS5828 and TAS5830. This also pulls in some gpiolib changes supporting shared GPIOs in the core there so we can convert some of the ASoC drivers open coding handling of that to the core functionality.
