Date: Mon, 31 Aug 2015 18:13:03 -0400 From: j.glisse@...il.com To: linux-kernel@...r.kernel.org Cc: Jérôme Glisse <jglisse@...hat.com>, Joerg Roedel <jroedel@...e.de>, iommu@...ts.linux-foundation.org Subject: [PATCH] iommu/amd: Fix amd_iommu_detect() (does not fix any issues). From: Jérôme Glisse <jglisse@...hat.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.
