commit 23f889bd upstream. This reverts commit 237ed86c. Our current implementation of live status check (repeat 9 times with 10ms delays between each attempt as a workaround for buggy displays) imposes a rather serious penalty, time wise, on intel_hdmi_detect(). Since we we already skip live status checks on platforms before gen 7, and since we seem to have coped quite well before the live status check was introduced for newer platforms too, the previous behaviour is probably preferable, at least unless someone can point to a use-case that the live status check improves (apart from "Bspec says so".)
