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

From: Ulrik De Bie <ulrik.debie-os@e2big.org>
commit 47eb0c8b4d9eb6368941c6a9bb443f00847a46d7 upstream.
The Lifebook E546 and E557 touchpad were also not functioning and worked after running:
echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled
Add them to the list of machines that need this workaround.
