Description

In the Linux kernel, the following vulnerability has been resolved:  drm/msm: Fix iommu_map_sgtable() return value check and avoid WARN  Commit "iommu: return full error code from iommu_map_sg[_atomic]()" changed iommu_map_sgtable() to return an ssize_t and negative values in error cases, rather than a size_t and a zero.  Store the return value in the appropriate type and in case of error, return it rather than WARNing.  Patchwork: https://patchwork.freedesktop.org/patch/719685/
