video: backlight: Remove useless BACKLIGHT_LCD_SUPPORT kernel symbol
Browse files Browse the repository at this point in the history 
We have two *_CLASS_DEVICE kernel config options (LCD_CLASS_DEVICE
and BACKLIGHT_LCD_DEVICE) that do the same job.
The patch removes useless BACKLIGHT_LCD_SUPPORT option
and converts LCD_CLASS_DEVICE into a menu.
