This exists one case, when pcm is closed and dev PM is waiting for autosuspend time expired to enter runtime suspend state. At the mean time, system is going to enter suspend, dev PM runtime suspend won't be called. It makes the rt9120 suspend consumption current not as expected. This patch can fix the rt9120 dev PM issue during runtime autosuspend and system suspend by binding dev PM runtime and ASoC component PM.
