This a request to get a quirk added upstream for the Synaptics ClickPad (buttonless trackpad) of the Lenovo Edge E440 to the synaptics kernel driver so the right coordinates for the surface corners are reported and the pointer functionality is correct.

Move one finger around the touchpad to detect the actual edges
Kernel says: x [1472..5044], y [1408..3398]
Touchpad sends: x [1024..5045], y [2457..4832] /^C
I will be attaching a patch tomorrow.
Similar changes have been requested for other Thinkpad models also shipping these new ClikcPads, via other distributions' bug trackers, forwarded upstream, and successfully incorporated in mainstream kernel code. See e.g.

Sorry for the noise, reassignign to 'linux' as this is related to the kernel synaptics driver.
