commit 8dfb839cfe737a17def8e5f88ee13c295230364a upstream.
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.
