The backlight is on for fb_blank eq FB_BLANK_UNBLANK, or off for any other value in fb_blank. But the field fb_blank in struct backlight_properties is deprecated and should not be used any longer. Replace the test for fb_blank in omap's backlight code with a simple boolean parameter and push the test into the update_status helper. Instead of reading fb_blank directly, decode the backlight device's status with backlight_is_blank().
