Is this patchset supposed to work without the renaming, correct?

If so consider dropping the drop of renames, taking required time
to organize with Derek and resubmit when things are ready:
there is no point for the rename to stall the rest and quit renaming
is not urgent at all.

Just for clarity is this supposed to fix this: https://gitlab.com/asus-linux/asusctl/-/issues/700 ?
This model works once in windows users disable  that new feature.

Note: that kernel the person submitting the bug is using contains your v8
