Egbert Eich 0706f17c30 drm/i915: Avoid race of intel_crt_detect_hotplug() with HPD interrupt, v2 ... An HPD interrupt may fire while we are in a function that changes the PORT_HOTPLUG_EN register - especially when an HPD interrupt storm occurs. Since the interrupt handler changes the enabled HPD lines when it detects such a storm the read-modify-write cycles may interfere. To avoid this, shiled the rmw cycles with IRQ save spinlocks. Changes since v1: - Implement a function which takes care of accessing PORT_HOTPLUG_EN.
