I did not do anything and I also have the following in dmesg:
[ 3.258973] I2C multi instantiate pseudo device driver CLSA0101:00: Error requesting irq at index 0: -22
[ 3.260295] I2C multi instantiate pseudo device driver: probe of CLSA0101:00 failed with error -22
However, I have nothing else. And you are right, the touchpad was fixed by that patch or that series of patches.
