Subject: [RFC][PATCH v2 09/13] iommu/arm-smmu-v3: Pass dev pointer to arm_smmu_detach_dev
Date: Mon, 30 Aug 2021 19:59:19 -0700 [thread overview]
Message-ID: <20210831025923.15812-10-nicolinc@nvidia.com> (raw)
In-Reply-To: <20210831025923.15812-1-nicolinc@nvidia.com>
We are adding NVIDIA implementation that will need a ->detach_dev()
callback along with the dev pointer to grab client information.
