Subject: Input: i8042 - add XMG C504 to keyboard reset table

From: Patrick Scheuring <[email protected]>

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:
