The policy we want to achieve is to disable runtime PM iff there is a device connected that doesn't have persist_enabled or a reset_resume() handler and whose parent/root hub resets on resume, right? So couldn't we remove the HCD-specific XHCI_RESET_ON_RESUME and set the (existing) generic USB_QUIRK_RESET_RESUME on the root hub instead? Then we could handle all of this in the USB core (during device initialization and when changing persist_enabled through sysfs) by just checking for udev->reset_resume on all parent hubs of the device in question (and use pm_runtime_get/put() on said device to prevent its parents from suspending as appropriate). -- 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
