[Impact]
Synaptics touchpad/trackpoint fail to work on Lenovo X1C5/6 and X280.
And they report they support intertouch mode through SMBus ver 3.
Current kernel driver limits RMI4 to SMBus 2.
[Fix]
Enable SMBus ver 3 and set them to SMBus mode will make synaptics work
fine.
[Test Case]
Tested on X1C5/6 and X280, confirm patches work fine.
[Regression Potential]
Enable RMI4 support on specific device ID, no regression is supposed.
Zesty and Xenial do not support this intertouch mode, so no need these
patches.

UBUNTU: SAUCE: Input: synaptics - add Intertouch support on X1 Carbon
6th and X280
Yiannis Marangos (2):
UBUNTU: SAUCE: Input: synaptics-rmi4 - RMI4 can also use SMBUS version
3
UBUNTU: SAUCE: Input: synaptics - Lenovo X1 Carbon 5 should use
SMBUS/RMI

<p>Looks fine. And if we really don't have time to wait for these
patches being merged to upstream first, I give Ack here.</p>
