[Intel-gfx] [PATCH 0/5] Fix recent watermark breakage

[Matt Roper]

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)
