drm-next-4.18-wip debug patch 1

So, the HDA device's usage counter is 0, it has no active children and runt=
ime
PM is allowed. Still, it's runtime active. Why is it not suspending? Here's=
 a
little patch which litters relevant code with debug printks, hopefully this
will get us closer to the answer. Could you apply this on top of
drm-next-4.18-wip and attach the resulting dmesg output?

Oh and could you also try:
cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status
... to double check that runtime PM is enabled?

Thanks!

You are the assignee for the bug.
