Subject: [PATCH v5 05/17] iommu: Use __iommu_group_set_domain() in iommu_change_dev_def_domain()
Date: Thu, 11 May 2023 01:42:03 -0300 [thread overview]
Message-ID: <5-v5-1b99ae392328+44574-iommu_err_unwind_jgg@nvidia.com> (raw)
In-Reply-To: <0-v5-1b99ae392328+44574-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.
