   267	 * @dev: Device
   268	 *
   269	 * This function looks for a DT node pointed to by a property named 'backlight'
   270	 * and uses of_find_backlight_by_node() to get the backlight device.
   271	 * Additionally if the brightness property is zero, it is set to
   272	 * max_brightness.

   274	 * Note: It is the responsibility of the caller to call put_device() when
   275	 * releasing the resource.
   276	 *
   277	 * Returns:
   278	 * NULL if there's no backlight property.
   279	 * Error pointer -EPROBE_DEFER if the DT node is found, but no backlight device
   280	 * is found.
   281	 * If the backlight device is found, a pointer to the structure is returned.
