# OneNetbook 4 has `GXTP7386:00 27C6:011A Stylus` exporting no buttons in 5.12
# and libinput does't consider it a tablet without them, but a touchscreen.
# This leads to real weird effects,
# starting from clicking as soon as the pen gets tracked.
# A kernel patch exists to resolve that, compiled as an out-of-tree module here
# to avoid recompiling the kernel for such a small change.
# `hid-multitouch-onenetbook4` is the fixed one, don't use `hid-multitouch`.
