Wacom tablets can share different physical sensors on one physical device. These are called siblings in the code. The current way of implementation relies on the USB topology to be able to share data amongs those sensors. We can replace the code to match a HID subsystem, without involving the USB topology: - the first probed sensor does not find any siblings in the list wacom_udev_list, so it creates its own wacom_hdev_data with its own struct hid_device - the other sensor checks the current list of siblings in wacom_hdev_data, and if there is a match, it associates itself to the matched device. To be sure that we are not associating different sensors from different physical devices, we also check for the phys path of the hid device which contains the USB topology.
