If anyone has any objections, please let me know. ------------------ From: Oleksandr Andrushchenko [ Upstream commit 02a0d9216d4daf6a58d88642bd2da2c78c327552 ] Some user-space applications expect multi-touch pressure on contact to be reported if it is advertised in device properties. Otherwise, such applications may treat reports not as actual touches, but hovering. Currently this is only advertised, but not reported. Fix this by not advertising that ABS_MT_PRESSURE is supported.
