One note, and this isn't due to your patches at all, but the touchscreen 
on the Thinkpad X13s needs to be manually bound in order to work via 
echo 1-0010 | sudo tee /sys/bus/i2c/drivers/i2c_hid_of/bind - this patch 
does not affect that, though I had hoped maybe it would.

Tested on the Lenovo Thinkpad X13s
