Subject: iommu/amd: Remove the unnecessary assignment
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=154e3a65f404cfd5fbb7f49df01905d4ad025264;p=linux.git

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().
