I didn't really have any latency issues on my X270 at all, I just
noticed the dmesg output because I routinely check dmesg when I upgrade
the kernel - I'm a bit sad like that. So I raised #875621 to have the
options enabled.

In fact with CONFIG_RMI4_SMB enabled and psmouse.synaptics_intertouch=1
(needed because my TouchPad isn't in the whitelist) I ran into issues
where my TrackPoint stopped working. I mailed
linux-input@vger.kernel.org[1] and all I got was someone suggesting
loading the modules in a specific order to restore functionality. I
ended up just disabling psmouse.synaptics_intertouch again.

1. https://www.spinics.net/lists/linux-input/msg53749.html

Then #880471 comes along where enabling CONFIG_RMI4_SMB breaks the
TouchPad on the ThinkPad X11e. I noticed that bug and commented that
because nothing improved for me, the new config may as well just be
disabled to avoid further regressions.

Not sure what to suggest here unless someone who is actually involved in
maintaining this stuff (and who knows how it works) steps up to help.

HTH,
Chris
