Subject: [PATCH 0/4] Fix checking of iommu_map_sgtable return value
Date: Tue, 21 Apr 2026 13:02:35 +0900 [thread overview]
Message-ID: <20260421-iommu_map_sgtable-return-v1-0-fb484c07d2a1@nvidia.com> (raw)
The return value of iommu_map_sgtable changed from unsigned to signed
quite a while ago, but not all callers were updated. Do that.
Each patch is independent of each other. The drm/msm patch additionally
changes from WARNing in case of mapping error to returning the error
code now available.
Best regards
Mikko
