Subject: [PATCH 6.12.y] ALSA: hda/tegra: Re-enable SDO workaround for Tegra194
Date: Mon,  5 Oct 2026 18:24:41 -0400	[thread overview]
Message-ID: <20261005222431.3492789-1-sashal@kernel.org> (raw)
In-Reply-To: <2026100518-penniless-browsing-d792@gregkh>

From: Aaron Kling <webgeek1234@gmail.com>

[ Upstream commit 89365897f4210979966aa808d7b013edf4080558 ]

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.

Fixes: 7f0ea5acfc19 ("arm64: tegra: Use correct compatible string for Tegra194 HDA")
