Subject: iommu/amd: Fix wrong check for ARRAY_SIZE()
X-Git-Tag: upstream/snapshot3+hdmi~6807^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;ds=sidebyside;h=2bd5ed002c0c493ac328f13a9e2a504261a7d48e;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

iommu/amd: Fix wrong check for ARRAY_SIZE()

The check in the for-loop is broken. Fix it and the
boot-crash it causes in AMD IOMMUv2 systems.
