Input: synaptics - enable SMBus for HP Elitebook 840 G2

[PATCH] Input: synaptics - enable SMBus for HP Elitebook 840 G2

Posted by Jonathan Denose 1 year, 6 months ago

The kernel reports that the touchpad for this device can support a
different bus.

With SMBus enabled the touchpad movement is smoother and three-finger
gestures are recognized.
