No counterpart to turn off?
turned off in runtime suspend during first explicit suspend call.
It's a refcount, hence it does matter how many times it's called. Does it really balance well? It smells suspicious if you add only a call to turn on without turning off...
Display power is turned ON during device probe. When soc codec probe completes, runtime suspend call is invoked and display power is turned OFF. So refcount is balanced.
