Subject: [PATCH v1 7/8] media: staging: media: tegra-vde: Use iommu_attach/detach_device()
Date: Thu,  6 Jan 2022 10:20:52 +0800	[thread overview]
Message-ID: <20220106022053.2406748-8-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20220106022053.2406748-1-baolu.lu@linux.intel.com>

Ordinary drivers should use iommu_attach/detach_device() for domain
attaching and detaching.
