[PATCH] Input: synaptics: enable InterTouch for ThinkPad L14 G1

[José Pekkarinen]

Observed on dmesg of my laptop I see the following
output:

[   19.898700] psmouse serio1: synaptics: queried max coordinates: x [..5678], y [..4694]
[   19.936057] psmouse serio1: synaptics: queried min coordinates: x [1266..], y [1162..]
[   19.936076] psmouse serio1: synaptics: Your touchpad (PNP: LEN0411 PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@xxxxxxxxxxxxxxx.

This patch will add its pnp id to the smbus list to
produce the setup of intertouch for the device. After
applying, the ouput will look like:
