Can you add a comment here explaining why this is OK? I think it is
easier that way to find out why this is here in the future instead of
going through the git blame history.
Sure, no problem.
I'll hold off sending a v3 though until you and Mathias can double check
everything in patch 2/2 is OK to take out and agree with that secondary logic
change.
Lets only enable it for xHCI 1.2 and controllers for now.
Avoiding unnecessary regressions.
So on Intel side the ALDER_LAKE*, RAPTOR_LAKE and METEOR_LAKE can be removed.
I'll double check other Intel hosts before submitting it forward
Thanks
