6.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jason Gunthorpe <jgg@xxxxxxxxxx>
[ 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'.
Fixes: b23e4fc4e3fa ("iommu: add Unisoc IOMMU basic driver")
