Subject: [PATCH 4.19 049/116] Input: synaptics - enable RMI on HP Envy 13-ad105ng

From: Yussuf Khalil <dev@...345.net>

commit 1369d0abe469fb4cdea8a5bce219d38cb857a658 upstream.

This laptop (and perhaps other variants of the same model) reports an
SMBus-capable Synaptics touchpad. Everything (including suspend and
resume) works fine when RMI is enabled via the kernel command line, so
let's add it to the whitelist.
