Subject: [PATCH] vfio/iommu_type1: replace kfree with kvfree
Git-commit: 2bed2ced40c97b8540ff38df0149e8ecb2bf4c65
Patch-mainline: v5.17-rc1
References: git-fixes
Variables allocated by kvzalloc should not be freed by kfree.
Because they may be allocated by vmalloc.
So we replace kfree with kvfree here.
Fixes: d6a4c185660c ("vfio iommu: Implementation of ioctl for dirty pages tracking")
