Subject: Input: elantech - add Fujitsu Lifebook E547 to force crc_enabled

From: Thorsten Leemhuis <[email protected]>

commit 704de489e0e3640a2ee2d0daf173e9f7375582ba upstream.

Temporary got a Lifebook E547 into my hands and noticed the touchpad only works after running:

	echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled

Add it to the list of machines that need this workaround.
