+Subject: Input: elantech - add support for newer elantech touchpads
+
+Newer elantech touchpads are not recognized by the current driver, since it
+fails to detect their firmware version number. This prevents more advanced
+touchpad features from being usable such as two-finger scrolling. This
+patch allows newer touchpads to be detected and be fully functional. Tested
+on Sony Vaio SVF13N17PXB.
