------------------

From: Wei Yang <richard.weiyang@gmail.com>

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.
