backlight: drop EARLY_EVENT_BLANK support
There was no users left - so drop the code to support EARLY_EVENT_BLANK. 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 <sam@ravnborg.org> Cc: Lee Jones <lee.jones@linaro.org> Cc: Daniel Thompson <daniel.thompson@linaro.org> Cc: Jingoo Han <jingoohan1@gmail.com> Cc: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: "Michał Mirosław" <mirq-linux@rere.qmqm.pl> Cc: Peter Rosin <peda@axentia.se> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: dri-devel@lists.freedesktop.org Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Daniel Thompson <daniel.thompson@linaro.org> Acked-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Acked-by: Lee Jones <lee.jones@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190725143224.GB31803@ravnborg.org
