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. References: https://bugzilla.kernel.org/show_bug.cgi?id=56661 Signed-off-by: Ash Willis <ashwillis@programmer.net> Signed-off-by: Rafael J.
