From 9f35421e09c494c36079d7cf5724ae9f832431d7 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 21 Feb 2011 11:17:35 +1000 Subject: drm/core: add ioctl to query device/driver capabilities We're coming to see a need to have a set of generic capability checks in the core DRM, in addition to the driver-specific ioctls that already exist. This patch defines an ioctl to do as such, but does not yet define any capabilities.
