Now my touchpad is recognized as full synaptics touchpad, and the touchscreen still works.
An additional, minor change: When the XPS12 screen is flipped, the touchpad is now not disabled, as was the case earlier. The keyboard is disabled as before.
I haven't noticed any side effects while working with this kernel in the past few weeks.
It would be great if these patches work their way into Trusty.
For simplification, you could use the kernel I compiled with the above patches from here:
