<pre>Yes, we need a runtime-pm reference, and we use the active engine-pm as that
also tells if it was idle and we can skip. The engine-pm put(wakeref) should be
irqsafe for this purpose.
I don't know what the lock->wait_lock is -- it doesn't look like one of ours,
which makes it more baffling how it got coupled into our wakeref.</pre>
