+Subject: [PATCH] Input: synaptics - fix regression with "image sensor"
+ trackpads
+
+commit 7968a5dd492ccc38345013e534ad4c8d6eb60ed1
+Input: synaptics - add support for Relative mode
+
+Accidentally broke support for advanced gestures (multitouch)
+on some trackpads such as the one in my ThinkPad X220 by
+incorretly changing the condition for enabling them. This
+restores it.
