--- Comment #1 from Kevin Brace <kevinbrace at gmx.com> ---
Added a new function called VIASetDFPBackLight to via_lvds.c.
This function turns the DFP (Digital Flat Panel) back light on or off.
Previously, DFP back light was not being turned off when the computer turns the
screen off, leading to unnecessary consumption of power.
This improvement is especially helpful in a mobile environment where conserving
power is key to extending battery life.
     The compiled device driver was tested on the following computer.

 - Epic 1314 laptop (MSI VR321 laptop equivalent, VN896 chipset) with Lubuntu
12.04 i386
