I must agree with this. The use case is very driver specific. But still, a common interface for setting needs_remote_wakeup would be useful. I believe most drivers using this right now will fail to do the 1 => 0 transition in a way which allows devices without remote wakeup support to autosuspend. Fixing all drivers can of course be done, but will probably have to be redone everytime a new driver is added. It's just not obvious that you need to wrap the change in usb_autopm_get/put_interface calls Bjørn -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
