Subject: drm/tegra: Support render node
Git-commit: 6c68b71776e760c67f10fbdbe56908793a7b1763
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
None of the driver-specific IOCTLs are privileged, so mark them as such
and advertise that the driver supports render nodes.
