Subject: [PATCH v3 12/22] iommu/amd: Pass iommu and devid to amd_iommu_make_clear_dte()
Date: Mon, 29 Jun 2026 15:35:25 +0000 [thread overview]
Message-ID: <20260629153535.15775-13-suravee.suthikulpanit@amd.com> (raw)
In-Reply-To: <20260629153535.15775-1-suravee.suthikulpanit@amd.com>
Take struct amd_iommu and device ID explicitly instead of deriving
the IOMMU from struct iommu_dev_data.
