Commit 46e831abe864 ("drm/i915/lpe: Mark LPE audio runtime pm as "no callbacks"") broke runtime PM with lpe audio. We can no longer runtime suspend the GPU since the sysfs power/control for the lpe-audio device no longer exists and the device is considered always active. We can fix this by not marking the device as active.
Do you also want to send with a HAX patch to force selection of SND_X86 for CI?
Hmm. Would have been a good idea a few minutes ago. Not sure I want to spam the list again. Depends how long it'll take to adjust the ci .config I suppose.
Trybot and link to the results?

The fi-byt-clapper pm tests passed which is the most significant result. For enabling LPE audio in CI, it appears we need to trick snd_hdmi_lpe_audio.ko into unloading on demand.
Re-ran the test for good measure after fixing the module unload in igt. Now all green.
