[PATCH] Input: synaptics - Enable RMI on HP Envy 13-ad105ng

[Yussuf Khalil]

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.

Are there issues with the touchpad when it works in the legacy (PS/2)
mode? I will be applying your patch, I just need to understand if it
needs to go into stable series, or we can just get it into 5.6 and later
versions.

Thanks!

Hi Dmitry,

I currently don't have access to the device anymore, but apart from 
missing gesture functionality, it seemed to have some issues with 
selecting text by clicking and moving the cursor when running in PS/2 
mode, so I guess it might be good to push the patch to stable.

Regards
