Paulo Zanoni d45a0bf549 drm/i915: grab the audio power domain when enabling audio on HSW+ ... With the current code, we unconditionally touch HSW_AUD_PIN_ELD_CP_VLD, which means we can touch it when the power well is off, and that will trigger an "Unclaimed register" message. Just adding the intel_crtc->config.has_audio should already avoid the unclaimed register messsages, but since we actually need the power well to make the Audio code work, it makes sense to also grab the audio power domain reference, and release it when it's not needed anymore. I used IGT's pm_rpm to reproduce this bug, but it can probably be reproduced on other tests that do modesets. I'm using a machine with eDP+HDMI connected.
