* Can the term “reference count” become relevant also for this commit message besides other possible adjustments?
* Can it be nicer to combine proposed updates for this software module as a patch series (with a cover letter)?
* Would you like to add the tag “Fixes”?

* Perhaps use the label “put_runtime” instead?
* Do you propose to perform an additional function call always (and not only according to failure cases)?
* How do you think about calling the function “pm_runtime_put_noidle”?
