| Subject: [PATCH] Input: elantech - add Fujitsu Lifebook E547 to force |
| crc_enabled |
| |
| 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. |
