From: Joerg Roedel Date: Fri, 18 Aug 2017 22:28:02 +0000 (+0200) Subject: iommu/amd: Fix compiler warning in copy_device_table() X-Git-Tag: v4.14-rc1~72^2^12~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ae162efbf2870c326e06b4f905423fb888f9cd2a;p=platform%2Fkernel%2Flinux-exynos.git iommu/amd: Fix compiler warning in copy_device_table() This was reported by the kbuild bot. The condition in which entry would be used uninitialized can not happen, because when there is no iommu this function would never be called. But its no fast-path, so fix the warning anyway.
