Subject: [PATCH 1/2] drm/tegra: Fix order of teardown in IOMMU case
Date: Mon, 23 Apr 2018 08:57:44 +0200	[thread overview]
Message-ID: <20180423065745.26102-1-thierry.reding@gmail.com> (raw)

From: Thierry Reding <treding@nvidia.com>

The original code works fine, this is merely a cosmetic change to make
the teardown order the reverse of the setup order.
