Subject: [PATCH 3.10 079/250] Input: i8042 - add Pegatron touchpad to noloop table

From: Marcos Paulo de Souza <marcos.souza.org@...il.com>

commit 41c567a5d7d1a986763e58c3394782813c3bcb03 upstream.

Avoid AUX loopback in Pegatron C15B touchpad, so input subsystem is able
to recognize a Synaptics touchpad in the AUX port.

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=93791
(Touchpad is not detected on DNS 0801480 notebook (PEGATRON C15B))
