The intend of this series is to simplify the runtime PM deployment in the phy core, but while doing that fixing a related problem for a Renesas SoC making use of a phy. This issue was raised by Geert Uytterhoeven and Yoshihiro Shimoda, due to a changed behaviour in the runtime PM core. The commit in question is f8817f61e821 (PM / runtime: Drop children check from __pm_runtime_set_status()). However, it turned out that the problem existed already prior this change, only that the error was printed instead of giving a WARN splat. More details about the changes are available in each change log.
