drm/simple-helpers: Always add planes to the state update 2016-08-25T18:46:03+00:00 Daniel Vetter daniel.vetter@ffwll.ch 2016-08-23T06:25:40+00:00 6dcf0de7ef10244b17442f47956a1d9fabe2abe1 Our update function is hooked to the single plane, which might not get called for crtc-only updates. Which is surprising, so fix this by always adding the plane. While at it document how&when the event should be sent out better in the kerneldoc.
