From 330682161d8702880ec72e9f4ea982deba9935dc Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Tue, 5 Mar 2024 17:22:35 +0100 Subject: [PATCH] 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 Cc: Robin van der Gracht Acked-by: Robin van der Gracht Acked-by: Andy Shevchenko Reviewed-by: Javier Martinez Canillas Link: https://lore.kernel.org/r/20240305162425.23845-3-tzimmermann@suse.de Signed-off-by: Lee Jones --- drivers/auxdisplay/ht16k33.c | 8 -------- 1 file changed, 8 deletions(-) diff --git a/drivers/auxdisplay/ht16k33.c b/drivers/auxdisplay/ht16k33.c index 96acfb2b58cd..82e55d61893b 100644 --- a/drivers/auxdisplay/ht16k33.c +++ b/drivers/auxdisplay/ht16k33.c @@ -295,16 +295,8 @@ static int ht16k33_bl_update_status(struct backlight_device *bl) return ht16k33_brightness_set(priv, brightness); } -static int ht16k33_bl_check_fb(struct backlight_device *bl, struct fb_info *fi) -{ - struct ht16k33_priv *priv = bl_get_data(bl); - - return (fi == NULL) || (fi->par == priv); -} - static const struct backlight_ops ht16k33_bl_ops = { .update_status = ht16k33_bl_update_status, - .check_fb = ht16k33_bl_check_fb, }; /*
