From 35577079b9943e158c7032afe1dde6faf4385222 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 23 Jan 2015 16:37:52 +0100 Subject: iommu/tegra: gart: Provide default ->map_sg() callback Commit 315786ebbf4a ("iommu: Add iommu_map_sg() function") adds a new ->map_sg() callback and provides a default implementation that drivers can use until they implement a hardware-specific variant. Unfortunately the Tegra GART driver was not updated as part of that commit, so that iommu_map_sg() calls on a domain provided by the GART cause an oops.
