The internal check_fb callback from struct pwm_bl_data is never implemented. The driver's implementation of check_fb always returns true, which is the backlight core's default if no implementation has been set. So remove the code from the driver. v2: * reword commit message Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://lore.kernel.org/r/20240305162425.23845-7-tzimmermann@suse.de Signed-off-by: Lee Jones <lee@kernel.org>
