3.8.13.14 -stable review patch.  If anyone has any objections, please let me 
know.

------------------

From: Johan Hovold <[email protected]>

commit 185d91442550110db67a7dc794a32efcea455a36 upstream.

The driver supports 16-bit brightness values, but the value returned
from get_brightness was truncated to eight bits.
