The corgi_lcd_limit_intensity() function is called from platform and defined in a driver, but the driver does not see the declaration: drivers/video/backlight/corgi_lcd.c:434:6: error: no previous prototype for 'corgi_lcd_limit_intensity' [-Werror=missing-prototypes] 434 | void corgi_lcd_limit_intensity(int limit) Move the prototype into a header that can be included from both sides to shut up the warning.
