From: Jiang Liu Date: Mon, 6 Jan 2014 06:18:13 +0000 (+0800) Subject: iommu/vt-d, trivial: print correct domain id of static identity domain X-Git-Tag: firefly_0821_release~176^2~4526^2^3~13 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9544c003e85f6ac6b0b617e15266fe2e81caa42a;p=firefly-linux-kernel-4.4.55.git iommu/vt-d, trivial: print correct domain id of static identity domain Field si_domain->id is set by iommu_attach_domain(), so we should only print domain id for static identity domain after calling iommu_attach_domain(si_domain, iommu), otherwise it's always zero.
