Subject: [PATCH 3.2 088/106] Input: i8042 - add Fujitsu Lifebook AH544 to
 notimeout list

3.2.93-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Daniel Drake <drake@...lessm.com>

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.
