Reading values from iio-sensor we are getting bad values. This matrix was added because the panel was a vertical one but the normal position is horizontal and the sensor is not bad oriented. Removing the matrix ensure we have correct orientation values and prevent from misleads where the incorrect values we were getting messed up. For example mutter actually is setting incorrect screen rotation for devices with panel orientation quirks. I'm pretty sure that there are more devices where we have incorrectly "corrected" the sensor values when the only problem was the panel orientation.

Files in this directory specify a description of hardware devices, in the form of mappings from modalias-like keys (which identify specific hardware devices) to udev properties. Files in this directory are not read by udev directly. Instead, man:systemd-hwdb(8) compiles them into a binary database. See man:hwdb(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of the udev daemon. Use 'systemd-analyze cat-config udev/hwdb.d' to display the effective config.
