From 4a23d0f9814c38308dc82b6dbc466666a400b27d Mon Sep 17 00:00:00 2001 From: Ashish Mhetre Date: Tue, 5 Dec 2023 11:30:45 +0530 Subject: [PATCH] memory: tegra: Protect SID override call under CONFIG_IOMMU_API tegra186_mc_client_sid_override() is protected under CONFIG_IOMMU_API. Call to this function is being made from tegra186_mc_resume() without any protection which is leading to build failure when CONFIG_IOMMU_API is not set. Fix this by protecting SID override function call from tegra186_mc_resume() under CONFIG_IOMMU_API.
