From: Geert Uytterhoeven <[email protected]> As of commit 45f0a85c8258741d11bda25c0a5669c06267204a ('PM / Runtime: Rework the "runtime idle" helper routine'), the return value of ->runtime_idle() is no longer ignored by the PM core, but used to decide whether to suspend the device or not.
Update the documentation to match the code.
