This behavior was introduced by the commit eb399d3c99d8 ("ALSA: hda - Skip ELD notification during PM process"). This skip may cause a problem, as we may miss the ELD update when the connection/disconnection happens right at the runtime-PM operation of the audio codec. Although this workaround was valid at that time, it's no longer true; the fix was required just because the ELD update procedure needed to wake up the audio codec, which had lead to a runtime-resume during a runtime-suspend. Meanwhile, the ELD update procedure doesn't need a codec wake up any longer since the commit 788d441a164c ("ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling"); i.e. there is no much reason for skipping the notification. Let's drop those checks for addressing the missing notification.
