Subject: [PATCH 5/6] iommufd/selftest: Set iommu_device for mock_device
Date: Wed, 8 Feb 2023 20:16:41 -0800 [thread overview]
Message-ID: <20230209041642.9346-6-yi.l.liu@intel.com> (raw)
In-Reply-To: <20230209041642.9346-1-yi.l.liu@intel.com>
From: Nicolin Chen <nicolinc@nvidia.com>
This is required to avoid NULL pointer when iommufd selftest tries to
allocate domain for mock_device.
