IIRC, we had suspend/resume issues with the T470 series, and had to
revert the change.

This one is not using RMI4 over SMBus (I have one of those). It is
using i2c-hid, so there is no need to add the PnPId of such devices.
The thing that needs to be checked when users are reporting is that
they have something in the report like:
[Tue Aug 28 17:13:59 2018] rmi4_smbus 22-002c: registering
SMbus-connected sensor

We had to revert this one too :/

I doubt this one is using RMI4 (Dell usually uses i2c-hid)

Thanks for gathering those data. I hope you'll be able to submit the
patch soon :)
