From: Benjamin Bara <benjamin.bara@xxxxxxxxxxx> When the optional fields "pressure_min" and "pressure_max" are not set, both fall back to 0, which results to the following libinput error: ADS7846 Touchscreen: kernel bug: device has min == max on ABS_PRESSURE Avoid it by only setting ABS_PRESSURE if the values differ.
