How do you think about a wording variant like the following?

   Change description:
   The PM runtime reference counter is generally incremented by a call of
   the function “pm_runtime_get_sync”.
   Thus call the function “pm_runtime_put_autosuspend” also in one error case
   to keep the reference counting consistent.


Would you like to add the tag “Fixes” to the commit message?

Markus
