    Subject[PATCH 3.12 146/235] Input: i8042 - add Pegatron touchpad to noloop table
    Date
    From: Marcos Paulo de Souza <marcos.souza.org@gmail.com>

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

    ===============

    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))
