I received it. I just didn't have the time to go over it in detail.
At first look, it seems correct...

Ehh... the code doesn't act as if it were a "possible" switch, but
rather that it _did_ find a x1_yoga-style switch, so the debug message
should be assertive to match the code:
pr_info("Tablet mode switch found (X1 Yoga style), Thinkpad is in...")
or something to that effect.
If the code is wrong, and it has false possitives, we enhance the
detection (possibly by using a quirk table if we must).
Care to respin with that change?
