From b8c157d3a9a13871742c8a8d3d4598c3791ed5f5 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 20 Oct 2010 10:39:35 +1000 Subject: drm/nouveau: only expose the object classes that are supported by the chipset We previously added all the available classes for the entire generation, even though the objects wouldn't work on the hardware.
