2021-11-10Input: elantench - fix misreporting trackpoint coordinatesPhoenix Huang1-0/+13
Some firmwares occasionally report bogus data from trackpoint, with X or Y displacement being too large (outside of [-127, 127] range). Let's drop such packets so that we do not generate jumps.

2021-04-10Input: elantech - Prepare a complete software node for the deviceHeikki Krogerus1-2/+4
Creating a software node and supplying that for the device instead of only the device properties in it. A software node was always created in any case to hold the additional device properties, so this change does not have any real effect. This change makes it possible to remove support for the problematic "dangling" device properties from i2c subsystem, i.e. the "properties" member from struct i2c_board_info. The problems caused by them are not related to this driver.
