2018-07-17HID: elan: Correctly report MT_PRESSURE instead of TOOL_WIDTHHans de Goede
Elan has given me a (GPL-ed) Android driver for their non HID-mt touchpads to help improve the upstream support. Acoording to Elan what we are currently reporting as tool-width really is a per-touch pressure. This always has a maximum of 255, so there is no need to make the max configurable.
