Bug description:
[Impact]
4.18+ kernel with Ubuntu 18.04.
libinput 1.10.4-1
xserver-xorg-input-libinput 0.27.1-1
tap-to-click is on by default.
After tapping on SYNA8005 (06CB:CD8C) for 50+ times, touchpad will be no
response when tapping.
[Fix]
libinput detect these taps as palm, so permanently disable tap-to-click.
upstream patch of libinput already fixed this issue:
commit 237ebb7cc4e9bf035891176acb08b1bf558ee989

touchpad: don't disable tapping on MT_TOOL_PALM
The tapping code can handle palm states now, so there is no need to
disable
tapping altogether when a tool-based palm is detected.
