Lenovo products have a pair of IDs, you'll want 21J6 [3] and 21MF [4] as
well. I submitted a patch myself [5], but I've been investigating another
symptom.

I have the same "wake on power removed" issue, but I have another issue
that's more annoying where the wifi just dies randomly. I only have the
wake issue when power is disconnected, not when power is connected again.
I mostly leave my device connected, so I only realized the behavior while
doing the regression testing requested in the other patch.
