Subject: [PATCH] iommu/amd: Fix amd_iommu_detect() (does not fix any issues).
Date: Mon, 31 Aug 2015 18:13:03 -0400 [thread overview]
Message-ID: <1441059183-9023-1-git-send-email-j.glisse@gmail.com> (raw)
From: Jérôme Glisse <jglisse@redhat.com>
Fix amd_iommu_detect() to return positive value on success, like
intended, and not zero. This will not change anything in the end
as AMD IOMMU disable swiotlb and properly associate itself with
devices even if detect() doesn't return a positive value.
