Hi Carl, Thank you for the heads up. I believe Jason's patchset 4 of 4 (http://www.spinics.net/lists/linux-input/msg29435.html) fixed the issue for your device and for other's. The patch was submitted last month. If you can test the set on your device and give us a Tested-by here, it will help Dmitry to merge the patch upstream. Thank you for your effort.
