It's entirely possibly that the other r375 code is relevant to r370 too, but I've not confirmed this, so I'll leave it where it is for now. NVIDIA's copyright headers maintained, as it's still all their code. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Gourav Samaiya <gsamaiya@nvidia.com>
