This patch removes the support in backlight, and drop the notifier in fbmem. That EARLY_EVENT_BLANK is not used can be verified that no driver set any of: lcd_ops.early_set_power() lcd_ops.r_early_set_power() Noticed while browsing backlight code for other reasons. v2: - Fix changelog to say "EARLY_EVENT_BLANK" (Daniel) Signed-off-by: Sam Ravnborg Cc: Lee Jones Cc: Daniel Thompson Cc: Jingoo Han Cc: Bartlomiej Zolnierkiewicz Cc: Daniel Vetter Cc: Sam Ravnborg Cc: Maarten Lankhorst Cc: "Michał Mirosław" Cc: Peter Rosin Cc: Gerd Hoffmann Cc: dri-devel@lists.freedesktop.org Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter Acked-by: Daniel Thompson Acked-by: Bartlomiej Zolnierkiewicz Acked-by: Lee Jones Link: https://patchwork.freedesktop.org/patch/msgid/20190725143224.GB31803@ravnborg.org --- drivers/video/backlight/lcd.c | 8 -------- drivers/video/fbdev/core/fbmem.c | 12 +----------- include/linux/fb.h | 4 ---- include/linux/lcd.h | 10 ---------- 4 files changed, 1 insertion(+), 33 deletions(-) (limited to 'include/linux') diff --git a/drivers/video/backlight/lcd.c b/drivers/video/backlight/lcd.c index d6b653aa4ee9..78b033358625 100644 --- a/drivers/video/backlight/lcd.c +++ b/drivers/video/backlight/lcd.c @@ -39,14 +39,6 @@ static int fb_notifier_callback(struct notifier_block *self, if (event == FB_EVENT_BLANK) { if (ld->ops->set_power) ld->ops->set_power(ld, *(int *)evdata->data); - } else if (event == FB_EARLY_EVENT_BLANK) { - if (ld->ops->early_set_power) - ld->ops->early_set_power(ld, - *(int *)evdata->data); - } else if (event == FB_R_EARLY_EVENT_BLANK) { - if (ld->ops->r_early_set_power) - ld->ops->r_early_set_power(ld, - *(int *)evdata->data); } else { if (ld->ops->set_mode) ld->ops->set_mode(ld, evdata->data); diff --git a/drivers/video/fbdev/core/fbmem.c b/drivers/video/fbdev/core/fbmem.c index 00fe0efeaee9..e6a1c805064f 100644 --- a/drivers/video/fbdev/core/fbmem.c +++ b/drivers/video/fbdev/core/fbmem.c @@ -1058,7 +1058,7 @@ int fb_blank(struct fb_info *info, int blank) { struct fb_event event; - int ret = -EINVAL, early_ret; + int ret = -EINVAL; if (blank > FB_BLANK_POWERDOWN) blank = FB_BLANK_POWERDOWN; @@ -1066,21 +1066,11 @@ fb_blank(struct fb_info *info, int blank) event.info = info; event.data = ␣ - early_ret = fb_notifier_call_chain(FB_EARLY_EVENT_BLANK, &event); - if (info->fbops->fb_blank) ret = info->fbops->fb_blank(blank, info); if (!ret) fb_notifier_call_chain(FB_EVENT_BLANK, &event); - else { - /* - * if fb_blank is failed then revert effects of - * the early blank event. - */ - if (!early_ret) - fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK, &event); - } return ret; } diff --git a/include/linux/fb.h b/include/linux/fb.h index 50948e519897..756706b666a1 100644 --- a/include/linux/fb.h +++ b/include/linux/fb.h @@ -135,10 +135,6 @@ struct fb_cursor_user { /* A display blank is requested */ #define FB_EVENT_BLANK 0x09 -/* A hardware display blank early change occurred */ -#define FB_EARLY_EVENT_BLANK 0x10 -/* A hardware display blank revert early change occurred */ -#define FB_R_EARLY_EVENT_BLANK 0x11 struct fb_event { struct fb_info *info; diff --git a/include/linux/lcd.h b/include/linux/lcd.h index 851eee8fff25..238fb1dfed98 100644 --- a/include/linux/lcd.h +++ b/include/linux/lcd.h @@ -41,16 +41,6 @@ struct lcd_ops { /* Get the LCD panel power status (0: full on, 1..3: controller power on, flat panel power off, 4: full off), see FB_BLANK_XXX */ int (*get_power)(struct lcd_device *); - /* - * Enable or disable power to the LCD(0: on; 4: off, see FB_BLANK_XXX) - * and this callback would be called proir to fb driver's callback. - * - * P.S. note that if early_set_power is not NULL then early fb notifier - * would be registered. - */ - int (*early_set_power)(struct lcd_device *, int power); - /* revert the effects of the early blank event. */ - int (*r_early_set_power)(struct lcd_device *, int power); /* Enable or disable power to the LCD (0: on; 4: off, see FB_BLANK_XXX) */ int (*set_power)(struct lcd_device *, int power); /* Get the current contrast setting (0-max_contrast) */ -- cgit v1.2.3-71-gd317
