+Subject: [PATCH] Input: wacom - make sure touch_max is set for touch devices
+
+Old single touch Tablet PCs do not have touch_max set at
+wacom_features. Since touch device at lease supports one
+finger, assign touch_max to 1 when touch usage is defined
+in its HID Descriptor and touch_max is not pre-defined.
