[PATCH 3.18 08/16] Input: i8042 - add Fujitsu Lifebook AH544 to notimeout list

From: Greg Kroah-Hartman
Date: Tue Jun 27 2017 - 08:50:54 EST


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

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

From: Daniel Drake <drake@xxxxxxxxxxxx>

commit 817ae460c784f32cd45e60b2b1b21378c3c6a847 upstream.

Without this quirk, the touchpad is not responsive on this product, with
the following message repeated in the logs:

psmouse serio1: bad data from KBC - timeout

Add it to the notimeout list alongside other similar Fujitsu laptops.
