From 6632863226d88383c9e2bedfeeb928ac7f8232b9 Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Wed, 9 Oct 2024 13:18:08 +0800 Subject: iommu: Remove iommu_present() The last callsite of iommu_present() is removed by commit <45c690aea8ee> ("drm/tegra: Use iommu_paging_domain_alloc()"). Remove it to avoid dead code.
