Subject: [PATCH 4.9 05/54] Input: i8042 - add nopnp quirk for Acer Aspire 5 A515

From: Jiri Kosina <jkosina@...e.cz>

commit 5fc27b098dafb8e30794a9db0705074c7d766179 upstream.

Touchpad on this laptop is not detected properly during boot, as PNP
enumerates (wrongly) AUX port as disabled on this machine.

Fix that by adding this board (with admittedly quite funny DMI
identifiers) to nopnp quirk list.
