From 117a1b903bafee02ef107c33f50d0c1cc91448c6 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Mon, 24 Jul 2023 14:36:05 -0300 Subject: [PATCH] iommu/sprd: Add missing force_aperture [ Upstream commit d48a51286c698f7fe8efc688f23a532f4fe9a904 ] force_aperture was intended to false only by GART drivers that have an identity translation outside the aperture. This does not describe sprd, so add the missing 'force_aperture = true'.
