4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Patrick Scheuring <patrick.scheuring.dev@gmail.com>
commit da25311c7ca8b0254a686fc0d597075b9aa3b683 upstream.
The Schenker XMG C504 is a rebranded Gigabyte P35 v2 laptop. Therefore it also needs a keyboard reset to detect the Elantech touchpad. Otherwise the touchpad appears to be dead.
With this patch the touchpad is detected:
$ dmesg | grep -E "(i8042|Elantech|elantech)"
