This series contains a fix for a problem which is very difficult to
reproduce under normal circumstances without specialized testing
hardware, along with a fix that seems to be required for some especially
rebellious GM45 laptops.

Lyude Paul (5):
  drm/i915: Fix possible race in intel_dp_add_mst_connector()
  drm/i915: Fix NULL deref when re-enabling HPD IRQs on systems with MST
  drm/i915: Fix threshold check in intel_hpd_irq_storm_detect()
  drm/i915: Clarify flow for disabling IRQs on storms
  drm/i915: Add short HPD IRQ storm detection for non-MST systems
