The patch removes this symbol as > useless and converts it into a menu. Something bothered me about the patch but I think its the lack of explanation in the patch header about *why* we don't use/need/want BACKLIGHT_LCD_SUPPORT. Essentially the reason BACKLIGHT_LCD_SUPPORT is useless is that we have two _CLASS_DEVICE configs (LCD_CLASS_DEVICE and BACKLIGHT_LCD_DEVICE) that do the same job (ad that do have code attached to them). It would be good to mention that in the patch header.
