This patch skips the default depop delay before D3 for Haswell (10 ms) and Valleyview2 (100 ms) display codec, to reduce codec suspend time.
The analog part of display audio is implemented in the external display. Some displays have weak pop noise while others not when suspending, no matter there is the default delay or not.
