From ad593827db9b73f15eb65416ec975ec0311f773a Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Mon, 15 May 2023 21:12:31 -0300 Subject: powerpc/iommu: Remove iommu_del_device() Now that power calls iommu_device_register() and populates its groups using iommu_ops->device_group it should not be calling iommu_group_remove_device(). The core code owns the groups and all the other related iommu data, it will clean it up automatically. Remove the bus notifiers and explicit calls to iommu_group_remove_device().
