This is because the power state of the device is only changed after the power state transition has taken place. The ``s_ctrl`` callback can be used to obtain device's power state after the power state transition: -.. c:function:: int pm_runtime_get_if_in_use(struct device *dev); +.. c:function:: int pm_runtime_get_if_active(struct device *dev); The function returns a non-zero value if it succeeded getting the power count or runtime PM was disabled, in either of which cases the driver may proceed to _______________________________________________ linuxtv-commits mailing list -- [email protected] To unsubscribe send an email to [email protected]
