To: dri-devel; +Cc: Dave Airlie, Christian König
We've been somewhat inconsistent when adding the new ioctl and
returned ENODEV instead of EOPNOTSUPPORTED upon failing the syncobj
capibility.
Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com>
Fixes: ea569910cbab98 ("drm/syncobj: add transition iotcls between binary and timeline v2")
Fixes: 01d6c357837918 ("drm/syncobj: add support for timeline point wait v8")
