auxdisplay: ht16k33: Remove struct backlight_ops.check_fb
The driver sets struct fb_info.bl_dev to the correct backlight device. Thus rely on the backlight core code to match backlight and framebuffer devices, and remove the extra check_fb() function from struct backlight_ops. v3: * use 'check_fb()' in commit message (Andy) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Robin van der Gracht <robin@protonic.nl> Acked-by: Robin van der Gracht <robin@protonic.nl> Acked-by: Andy Shevchenko <andy@kernel.org> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://lore.kernel.org/r/20240305162425.23845-3-tzimmermann@suse.de Signed-off-by: Lee Jones <lee@kernel.org>
