Subject: iommu/sprd: Add missing force_aperture
X-Git-Tag: v5.15.132~243
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=de4aca5b284ebf3d4d9e29f8158fdcda1ef00d0a;p=thirdparty%2Fkernel%2Fstable.git

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'.
