in current code.

 * from broken hardware triggering massive amounts of interrupts and grinding

 * the system to a halt.

 * Current implementation expects that hotplug interrupt storm will not be

 * seen when display port sink is connected, hence on platforms whose DP

 * callback is handled by i915_digport_work_func reenabling of hpd is not

 * performed (it was never expected to be disabled in the first place ;) )

 * this is specific to DP sinks handled by this routine and any other display

 * such as HDMI or DVI enabled on the same port will have proper logic since

 * it will use i915_hotplug_work_func where this logic is handled.
