Hi Rafael, I was wondering why PM Runtime Core cannot call the device PM callbacks when its device's bus does not support runtime PM (if such a scenario is valid)? Regards, Nithish Mahalingam P.S. Alan, Not sure if you are askin the a similar question in the "System sleep vs. runtime PM" mail thread. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
