Since FB_TFT selects FB_BACKLIGHT there's no need for this conditional so just remove it and we're good. Fixes: b4a1ed0cd18b ("fbdev: make FB_BACKLIGHT a tristate") Cc: Signed-off-by: Noralf Trønnes Acked-by: Sam Ravnborg --- Changes since v1: - No need for the #ifdef at all since FB_BACKLIGHT is always selected - Fix fb_ssd1351 as well fb_watterott has the same problem, but I've sent a removal patch for that one. drivers/staging/fbtft/fb_ssd1351.c | 4 ---- drivers/staging/fbtft/fbtft-core.c | 9 +-------- 2 files changed, 1 insertion(+), 12 deletions(-) diff --git a/drivers/staging/fbtft/fb_ssd1351.c b/drivers/staging/fbtft/fb_ssd1351.c index cf263a58a148..6fd549a424d5 100644 --- a/drivers/staging/fbtft/fb_ssd1351.c +++ b/drivers/staging/fbtft/fb_ssd1351.c @@ -187,7 +187,6 @@ static struct fbtft_display display = { }, }; -#ifdef CONFIG_FB_BACKLIGHT static int update_onboard_backlight(struct backlight_device *bd) { struct fbtft_par *par = bl_get_data(bd); @@ -231,9 +230,6 @@ static void register_onboard_backlight(struct fbtft_par *par) if (!par->fbtftops.unregister_backlight) par->fbtftops.unregister_backlight = fbtft_unregister_backlight; } -#else -static void register_onboard_backlight(struct fbtft_par *par) { }; -#endif FBTFT_REGISTER_DRIVER(DRVNAME, "solomon,ssd1351", &display); diff --git a/drivers/staging/fbtft/fbtft-core.c b/drivers/staging/fbtft/fbtft-core.c index ed992ca605eb..1690358b8f01 100644 --- a/drivers/staging/fbtft/fbtft-core.c +++ b/drivers/staging/fbtft/fbtft-core.c @@ -128,7 +128,6 @@ static int fbtft_request_gpios(struct fbtft_par *par) return 0; } -#ifdef CONFIG_FB_BACKLIGHT static int fbtft_backlight_update_status(struct backlight_device *bd) { struct fbtft_par *par = bl_get_data(bd); @@ -161,6 +160,7 @@ void fbtft_unregister_backlight(struct fbtft_par *par) par->info->bl_dev = NULL; } } +EXPORT_SYMBOL(fbtft_unregister_backlight); static const struct backlight_ops fbtft_bl_ops = { .get_brightness = fbtft_backlight_get_brightness, @@ -198,12 +198,7 @@ void fbtft_register_backlight(struct fbtft_par *par) if (!par->fbtftops.unregister_backlight) par->fbtftops.unregister_backlight = fbtft_unregister_backlight; } -#else -void fbtft_register_backlight(struct fbtft_par *par) { }; -void fbtft_unregister_backlight(struct fbtft_par *par) { }; -#endif EXPORT_SYMBOL(fbtft_register_backlight); -EXPORT_SYMBOL(fbtft_unregister_backlight); static void fbtft_set_addr_win(struct fbtft_par *par, int xs, int ys, int xe, int ye) @@ -853,13 +848,11 @@ int fbtft_register_framebuffer(struct fb_info *fb_info) fb_info->fix.smem_len >> 10, text1, HZ / fb_info->fbdefio->delay, text2); -#ifdef CONFIG_FB_BACKLIGHT /* Turn on backlight if available */ if (fb_info->bl_dev) { fb_info->bl_dev->props.power = FB_BLANK_UNBLANK; fb_info->bl_dev->ops->update_status(fb_info->bl_dev); } -#endif return 0;
