[PATCH 0/4] Fix checking of iommu_map_sgtable return value

Posted by Mikko Perttunen 1 month, 3 weeks ago

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
