Subject: [PATCH 6/6 v2] PM / Runtime: Replace "run-time" with "runtime" in documentation
From: Rafael J. Wysocki <rjw@...k.pl>
The runtime PM documentation and kerneldoc comments sometimes spell
"runtime" with a dash (i.e. "run-time"). Replace all of those
instances with "runtime" to make the naming consistent.
