[PATCH libinput 2/2] tablet: use libwacom_new_from_path() to handle more tablets

[Peter Hutterer]

Some tablets cannot be differentiated by pid/vid alone, use the device path
instead - that gives libwacom the ability to extract the information required
to handle the device (libwacom doesn't open the path, it just reads through
the sysfs entry of the device).
