From 89365897f4210979966aa808d7b013edf4080558 Mon Sep 17 00:00:00 2001 From: Aaron Kling Date: Sat, 26 Sep 2026 02:24:19 -0500 Subject: [PATCH] ALSA: hda/tegra: Re-enable SDO workaround for Tegra194 This workaround was originally added for Tegra194, but no longer gets applied for it. Commit 615d43540043 ("ALSA: hda/tegra: fix tegra-hda on tegra30 soc") changed the guard to tegra30-hda, which worked because all affected archs had the fallback compatible. However, commit 7f0ea5acfc19 ("arm64: tegra: Use correct compatible string for Tegra194 HDA") removed the fallback compatible for Tegra194, causing this to break.
