Subject: [PATCH] drm/tegra: Fix ordering of cleanup code
Date: Wed, 25 Sep 2019 13:26:59 +0200 [thread overview]
Message-ID: <20190925112659.2048-1-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
Commit Fixes: b9f8b09ce256 ("drm/tegra: Setup shared IOMMU domain after
initialization") changed the initialization order of the IOMMU related
bits but didn't update the cleanup path accordingly. This asymmetry can
cause failures during error recovery.
