From: Matt Walker <matt.g.d.walker@xxxxxxxxx> Added detection for newer Elantech touchpads, so that kernel doesn't fall-back to default PS/2 driver. Supports touchpads released after ~August 2013. Fixes bug: https://lists.launchpad.net/kernel-packages/msg18481.html Tested-by: Matt Walker <matt.g.d.walker@xxxxxxxxx> on an Acer Aspire S7-392-6302 ---- Thanks to Hauke for the reference on how to submit a patch properly. Please let me know if additional modifications are required.
