And when resuming from suspend mode, it checks hda controller & codec status to detect headphone hotplug event. Now this patch does the same job in SOF runtime pm functions. And we need to check all the non-hdmi codecs for some cases like playback with HDMI or capture with DMIC connected to dsp. In these cases, only controller is active and codecs are suspended, so codecs can't send unsolicited event to controller. The jack polling operation will activate codecs and unsolicited event can work even codecs become suspended later. Tested on whiskylake with hda codecs.
