    Subject[patch 34/41] video: always update the brightness when poking "brightness"
    2.6.27-stable review patch.  If anyone has any objections, please let us know.

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

    From: Zhang Rui <rui.zhang@intel.com>

    commit 9e6dada9d255497127251c03aaa59296d186f959 upstream.

    always update props.brightness no matter the backlight is changed
    via procfs, hotkeys or sysfs.
