Subject: [ 101/262] gma500: Fix regression on Oaktrail devices

From: Greg KH <gregkh@...uxfoundation.org>

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

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

From: Alan Cox <alan@...ux.intel.com>

commit 26df641eac05abe1a3276eea441359b4d1120816 upstream.

The register map patches didn't set one value for the GMA600 which
means the Fujitsu Q550 dies on boot with the GMA500 driver enabled.

Add the map entry so we don't read from the device MMIO + 0 by mistake.
