Subject: Input: elantech - add Fujitsu Lifebook E546/E557 to force crc_enabled

From: Ulrik De Bie <[email protected]>

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.
