If anyone has any objections, please let me know. ------------------ From: Wei Yang commit 5c365d18a73d3979db37006eaacefc0008869c0f upstream. In 'commit <55d940430ab9> ("iommu/vt-d: Get rid of domain->iommu_lock")', the error handling path is changed a little, which makes the function always return 0. This path fixes this.
