drm: Add a SET_CLIENT_CAP ioctl
This ioctl can be used to turn some knobs in a DRM driver. The client can ask the DRM core for an alternate view of the reality: it can be useful to be able to instruct the core that the DRM client can handle new functionnality that would otherwise break current ABI. v2: Rename to ioctl from SET_CAP to SET_CLIENT_CAP (Chris Wilson) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
