Subject: [PATCH AUTOSEL 4.14 21/21] Input: synaptics - enable RMI mode for X1 Extreme 2nd Generation

From: Lyude Paul <lyude@...hat.com>

[ Upstream commit 768ea88bcb235ac3a92754bf82afcd3f12200bcc ]

Just got one of these for debugging some unrelated issues, and noticed
that Lenovo seems to have gone back to using RMI4 over smbus with
Synaptics touchpads on some of their new systems, particularly this one.
So, let's enable RMI mode for the X1 Extreme 2nd Generation.
