This reverts commit 994efacdf9a087b52f71e620b58dfa526b0cf928. The justification is that if hw blanking fails (i.e. fbops->fb_blank) fails, then we still want to shut down the backlight. Which is exactly _not_ what fb_blank() does and so rather inconsistent if we end up with different behaviour between fbcon and direct fbdev usage. Given that the entire notifier maze is getting in the way anyway I figured it's simplest to revert this not well justified commit.
