Subject: [PATCH v2 09/22] media: nvidia: tegra: Use iommu_paging_domain_alloc()
Date: Tue, 4 Jun 2024 09:51:21 +0800 [thread overview]
Message-ID: <20240604015134.164206-10-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20240604015134.164206-1-baolu.lu@linux.intel.com>
An iommu domain is allocated in tegra_vde_iommu_init() and is attached to
vde->dev. Use iommu_paging_domain_alloc() to make it explicit.
