Thanks!
I did not spot anything suspicious in the i2c-hid initialization. When the issue happens, can you check what the pin state is and if it changes when you use the touchpad? If I read your ACPI tables right, something like this:
# grep GPIO_18 /sys/kernel/debug/pinctrl/INT3452:00/pins
(it could be another INT3452:* device as well).
The GPIO line should be high and when the touchpad is pressed it should go low.
Then another thing, if you unload i2c-hid and load it back, does it start working again?
# modprobe -r i2c-hid # modprobe i2c-hid
