/* The backlight_* functions must be present in the API regardless whether
* HAVE_BACKLIGHT is defined or not. The reason is that the stock Ondio has
* no backlight but can be modded to have backlight (it's prepared on the
* PCB). This makes backlight an all-target feature API wise, and keeps API
* compatible between stock and modded Ondio.
* For OLED targets like the Sansa Clip, the backlight_* functions control
* the display enable, which has essentially the same effect. */
