commit 4dd8752a14ca0303fbdf0a6c68ff65f0a50bd2fa upstream.
The runtime PM state should not be changed by drivers that do not implement runtime PM even if it happens to work around a bug in PM core.
With the wake irq arming now fixed, drop the bogus runtime PM state update which left the device in active state (and could potentially prevent a parent device from suspending).
