2023-06-27backlight/gpio_backlight: Rename field 'fbdev' to 'dev'Thomas Zimmermann
Rename the field 'fbdev' in struct gpio_backlight_platform_data and struct gpio_backlight to 'dev', as they store pointers to the Linux platform device; not the fbdev device. Makes the code easier to understand.

2017-08-07backlight: gpio_backlight: Delete pdata inversionLinus Walleij
The option to invert the output of the GPIO (active low) is not used by the only platform still using platform data to set up a GPIO backlight (one SH board). Delete the option as we do not expect to expand the use of board files for this driver, and GPIO descriptors intrinsically keep track of any signal inversion.
