Subject: [PATCH 4.14 14/52] Input: synaptics - Lenovo Carbon X1 Gen5 (2017) devices should use RMI

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dmitry Torokhov <dmitry.torokhov@...il.com>

commit 9b2071028f8def49971a3b213ab6efd02a7e56e8 upstream.

The touchpad on Lenovo Carbon X1 Gen 5 (2017 - Kabylake) is accessible over
SMBUS/RMI, so let's activate it by default.
