This does not affect suspend_blockers nor does suspend_blockers
interfere with that.
Suspend_blockers allow the system to suspend ("mem">/sys/power/state
suspend), when the userspace decides that the device is not in use.
So implementing suspend_blockers support does not impact any
optimizations done to either system A nor system B.
