I have same bug on thinkpad t440s.
And that fix works for me:
```
# /etc/systemd/system/touchpad-sleep.service
# restore touchpad on suspend

[Unit]
Description=Restore Touchpad on suspend
Before=sleep.target
StopWhenUnneeded=yes

[Service]
#Type=oneshot
Type=idle
RemainAfterExit=yes
ExecStart=/bin/bash -c 'echo "0000:00:1f.4" > 
/sys/bus/pci/drivers/i801_smbus/unbind'
ExecStop=/bin/bash -c 'echo "0000:00:1f.4" > 
/sys/bus/pci/drivers/i801_smbus/bind'

[Install]
WantedBy=sleep.target
```
