If anyone has any objections, please let me know. ------------------ From: Paul Fertser commit d8f8a74d5fece355d2234e1731231d1aebc66b38 upstream. This command was sent behind serio's back and the answer to it was confusing atkbd probe function which lead to the elantech touchpad getting detected as a keyboard. To prevent this from happening just let every party do its part of the job.
