<pre>CI reported a few failures on BSW/BYT systems after taking the patch to IGT
from Chris.
This shows that there is 1 reference remaining even after disabling all the
screens. Also, like you pointed out earlier, there is a reference from the
audio driver that is not present in successful runs.
Wakeref x1 taken at:
intel_display_power_get+0x18/0x50 [i915]
i915_audio_component_get_power+0x11/0x20 [i915]
snd_hdac_display_power+0x6a/0x100 [snd_hda_core]
hda_codec_runtime_resume+0x52/0x60 [snd_hda_codec]
pm_runtime_force_resume+0x6a/0xd0
dpm_run_callback+0x64/0x280
device_resume+0xb3/0x1e0
async_resume+0x14/0x40
But, why would this reference be taken only in the failure cases that happens
only in some of the runs?
