I still think that the child device should inherit its parent's async_suspend flag to do the asynchronous resume more efficiently. or at least we should provide such an interface in drivers/base/power/common.c, so that device can tell the device core to inherit this flag if there is no off-tree dependency. thanks, rui > Thanks, > Rafael > -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
