From 154e3a65f404cfd5fbb7f49df01905d4ad025264 Mon Sep 17 00:00:00 2001 From: Adrian Huang Date: Wed, 22 Jan 2020 22:36:29 +0800 Subject: [PATCH] iommu/amd: Remove the unnecessary assignment The assignment of the global variable 'iommu_detected' has been moved from amd_iommu_init_dma_ops() to amd_iommu_detect(), so this patch removes the assignment in amd_iommu_init_dma_ops().
