That is, a patch like below could work for the recent chips yes, it is still needed. The newer chips (GLK, ICL and newer) have added sw logic in i915 get_power() that must be run before audio controller is initialized. So calling display_power() here is actually more critical than before, power up from codec driver is too late. If it's not done, you'll get verbs timing out (unless power management is disabled on i915 side).
