Subject[ 62/99] ACPI / video: ignore BIOS initial backlight value for Fujitsu E753
Date
3.10-stable review patch.  If anyone has any objections, please let me know.

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

From: Lan Tianyu <tianyu.lan@intel.com>

commit 9657a565a476d517451c10b0bcc106e300785aff upstream.

The BIOS of FUjitsu E753 reports an incorrect initial backlight value
for WIN8 compatible OS, causing backlight to be dark during startup.
This change causes the incorrect initial value from BIOS to be ignored.
