Change subject: SKL: add ACPI brightness control
......................................................................

Patch Set 4:

I should note that this patch was adapted from a series of commits from google's eve-campfire branch, and was a quick/dirty way for me to get ACPI brightness controls working for SKL/KBL devices. A better way would likely be to make use of the existing  code under drivers/intel/gma, but would be a little more work.

There's also CB:31503 which provides the asl portion for the GMA driver.
