Subject: [PATCH v2 2/3] iommu/amd: Don't call report_iommu_fault()
Date: Thu, 6 Nov 2025 16:34:58 -0400 [thread overview]
Message-ID: <2-v2-25fc75484cab+ab-iommu_set_fault_jgg@nvidia.com> (raw)
In-Reply-To: <0-v2-25fc75484cab+ab-iommu_set_fault_jgg@nvidia.com>
This old style API is only used by drivers/gpu/drm/msm,
drivers/remoteproc/omap_remoteproc.c, and
drivers/remoteproc/qcom_q6v5_adsp.c none are used on x86 HW.
Remove the dead code to discourage new users.
