Subject: [PATCH v2 05/14] iommu: Use __iommu_group_set_domain() in iommu_change_dev_def_domain()
Date: Wed, 29 Mar 2023 20:40:29 -0300 [thread overview]
Message-ID: <5-v2-cd32667d2ba6+70bd1-iommu_err_unwind_jgg@nvidia.com> (raw)
In-Reply-To: <0-v2-cd32667d2ba6+70bd1-iommu_err_unwind_jgg@nvidia.com>
This is missing re-attach error handling if the attach fails, use the
common code.
The ugly "group->domain = prev_domain" will be cleaned in a later patch.
