[PATCH] [PATCH] Input: Disable Intertouch for Lenovo T14 and P14s AMD G1

[PATCH] [PATCH] Input: Disable Intertouch for Lenovo T14 and P14s AMD G1

[Mark Pearson]

Since intertouch was enabled for the T14 and P14s AMD G1 laptops there
have been a number of reports of touchpads not working well.

Debugging this with Synaptics they noted that intertouch should not be
enabled as SMBUS host notify is not available on these laptops.

Reverting the previous commit (e4ce4d3a939d97bea045eafa13ad1195695f91ce)
to restore functionality back to what it was.

Note - we are working with Synaptics to see if there is a better
solution, but nothing is confirmed as yet.

Resending as I hadn't seen any reviews. I think this didn't make it on
the list as I can't see it on the archives :(

Please let me know if there are any concerns.

Thanks
Mark

I believe this is commit 2fd003ee8ade6b7f2777becc6f9917d7c313784f and it
should be part of 6.0 release.

Thanks.
