[PATCH 4.4 12/38] drivers: staging: nvec: remove bogus reset command for PS/2 interface

From: Greg Kroah-Hartman
Date: Thu Nov 17 2016 - 05:40:38 EST


4.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Paul Fertser <fercerpav@xxxxxxxxx>

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.
