I can't test myself since I don't have the correct hardware, BUT this change seems to work for him. I'm thinking he has an early version of the X1E which may use slightly different trackpad revision.

Who is "him"? Do you have a bug-report link or some such ?

With which kernel version is this ?  Could it be that the commit you are reverting was
backported to a stable-series release while that stable series is missing the rmi4
updates necessary to make things work on newer models ?

What are the symptoms / problems "him" is seeing when not reverting this?

On case it is not clear: NACK due to insufficient information why this is
necessary / missing description and root cause analysis of the actual problem.

Regards,

Hans

p.s.

My apologies if this sounds a bit grumpy, I got out of bed on the wrong side this morning.

This removes two totally separate models for "one guy on Reddit". Does
he have two computers that coincidentally have the same problem? Any
details about what that problem is so that we can assess it?
