> pch}_fifo_underrun_reporting() to intel_display
>
> Going forward, struct intel_display is the main display device data pointer.
> Convert intel_set_cpu_fifo_underrun_reporting() and
> intel_set_pch_fifo_underrun_reporting() to struct intel_display, along with
> some of the call chains from there.
