Subject: [PATCH v11 1/6] iommu: Add note about struct iommu_fwspec usage
Date: Thu, 17 Nov 2022 19:27:15 +0100 [thread overview]
Message-ID: <20221117182720.2290761-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20221117182720.2290761-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
This structure is to be considered private to the IOMMU API. Except for
very few exceptions, IOMMU consumer drivers should treat this as opaque
data.
