Uhh looks like we messed up a bit with integration. Now droid4 LCD backlight can no longer be enabled at all manually in v5.6-rc1 without the "add led-backlight driver" patch.. Should we just merge it to fix it rather than start scrambling with other temporary hacks? I don't care if we use "default-brightness", or if we use "default-brightness-level". The binding merged says now "default-brightness", so let's go with that one. That's what other LED drivers are using too.
