From d61a06862ba8c14466e1dd718cac460da0465ddd Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 4 Jul 2011 03:16:17 +0000 Subject: [PATCH] drm/kms: allow drm_mode_group with no objects Sometimes we could be controlling a device (such as an NVIDIA Tesla) that has no crtcs/encoders/connectors. One could argue that the driver should unset DRIVER_MODESET in this case, but that changes a whole heap of the DRM's other behaviours, and it's much easier to just be a modesetting driver without any outputs.
