| parent | drm/i915: Only run commit when crtc is active, v2. (diff) | |
drm/i915: Only call commit_planes when there are things to commit.
The atomic helpers set planes_changed on a crtc_state if there is
any plane_state bound to that crtc. If there's none and there is
no pipe update required the crtc has nothing to update, so vblank
evasion can be skipped.
