In case it's not obvious, the quirk necessary for the Apple T2 was submitted by Aditya here: https://lore.kernel.org/r/20261010172301.12764-1-aditya.garg@linux.dev/ Also, Jason attached a functionally identical patch to this e-mail: https://lore.kernel.org/r/CABZrw2H+3yt2Y7xiq6OyAWaJM7P9ox-2nJxoQuJMwoJHLgi+YQ@mail.gmail.com/ Either patch is a viable fix for this problem.
