Backlight blank status is now tracked exclusively in struct backlight_properties.state. The core backlight code keeps the fb_blank and state fields in sync, but doesn't do anything else with fb_blank. Several drivers initialize fb_blank to FB_BLANK_UNBLANK to enable the backlight. This is already the default for the state field. So we can delete the fb_blank code from core and drivers and rely on the state field.
