Subject: [PATCH] iommu/vt-d: return error code in domain_context_mapping_one()
Date: Wed, 13 Jul 2016 13:53:21 +0000 [thread overview]
Message-ID: <1468418001-19089-1-git-send-email-richard.weiyang@gmail.com> (raw)
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.
