+
+Moreover, the driver core prevents runtime PM callbacks from racing with the bus

+notifier is used by some subsystems to carry out operations affecting the
+runtime PM functionality. It does so by calling pm_runtime_get_sync() before

+To allow bus types and drivers to put devices into the suspended state by

+executes pm_runtime_put_sync() after running the BUS_NOTIFY_UNBIND_DRIVER
+notifications in __device_release_driver(). This requires bus types and
+drivers to make their ->remove() callbacks avoid races with runtime PM directly,
+but also it allows of more flexibility in the handling of devices during the
+removal of their drivers.

it at run time by changing the value of its /sys/devices/.../power/control
