3.6.11.6 stable review patch. If anyone has any objections, please let me know. ------------------ From: Ash Willis <ashwillis.kernel@xxxxxxxxx> [ Upstream commit 780a6ec640a3fed671fc2c40e4dd30c03eca3ac3 ] This patch addresses kernel bug 56661. BIOS reports an incorrect backlight value, causing the driver to switch off the backlight completely during startup. This patch ignores the incorrect value from BIOS.
