Subject: Input: elantech - add Fujitsu Lifebook E547 to force crc_enabled
From: Thorsten Leemhuis <linux@leemhuis.info>
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.
