.init_gpu_characteristics implementations were always returning 0 for all GPUs, so signature was changed to return void. JIRA NVGPU-677 Change-Id: Ibfeb0b73e1e8f0b5b7e4db1de7e190268368568f Signed-off-by: Nicolas Benech <nbenech@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1998808 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
