From 6d026e6d48cd2a95407c8fdd8d6187b871401c23 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Thu, 14 Nov 2024 10:42:29 -0700 Subject: [PATCH] iommu/arm-smmu-v3: Import IOMMUFD module namespace Commit 69d9b312f38a ("iommu/arm-smmu-v3: Support IOMMU_VIOMMU_ALLOC") started using _iommufd_object_alloc() without importing the IOMMUFD module namespace, resulting in a modpost warning: WARNING: modpost: module arm_smmu_v3 uses symbol _iommufd_object_alloc from namespace IOMMUFD, but does not import it. Commit d68beb276ba2 ("iommu/arm-smmu-v3: Support IOMMU_HWPT_INVALIDATE using a VIOMMU object") added another warning by using iommufd_viommu_find_dev(): WARNING: modpost: module arm_smmu_v3 uses symbol iommufd_viommu_find_dev from namespace IOMMUFD, but does not import it. Import the IOMMUFD module namespace to resolve the warnings.
