From: Paul Fertser <fercerpav@gmail.com>

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.
