From eb43004087507e71e7294fb786b715ae81242c34 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 4 Sep 2015 14:40:32 +1000 Subject: drm: remove unnecessary usage of object handles No longer required in a lot of cases, as objects are identified over NVIF via an alternate mechanism since the rework.
