Touchscreen: ID 04f3:0381 Elan Microelectronics Corp.

Kernels booted in Ubuntu 15.10 using kernel bisect debug method.
By kernel version number:
Touchscreen on 4.1.10-unstable works: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1.10-unstable/
Touchscreen on 4.2-rc1-unstable is broken: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-rc1-unstable/

Finding the commit that caused the problem might be difficult using "git
bisect" on kernel source code because the SSD in my laptop is too small.
I could use a large external drive to do this. Need to make sure if
there are any more debug steps to make this job faster or easier.
