From eac93f4d4ec63423704657895ce9a4ddac7b023b Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 12 Jul 2024 16:35:25 +0100 Subject: iommu/tegra-smmu: Pass correct fwnode to iommu_fwspec_init() iommu_fwspec_init() expects to receive the fwnode corresponding to the IOMMU device, not the fwnode corresponding to the client device being probed. Fix arm_smmu_configure() to pass the correct fwnode to iommu_fwspec_init().
