A couple recent changes to the display watermark code by Tvrtko and me haven't
played well together and resulted in a situation where we can miscalculate
watermarks or even panic the kernel by disabling/enabling the primary display
plane. This series should clean up the problem areas and prevent these issues
until the proper atomic watermark rework is ready.
Matt Roper (5):
drm/i915: Ensure crtc_state backpointer is initialized
drm/i915: Kill intel_crtc->active
drm/i915: Update intel_crtc_active() to use state values
drm/i915: Use crtc->state->active in ilk/skl watermark calculations
drm/i915: Don't assume primary & cursor are always on for wm
calculation (v3)
