Subject: [PATCH] rosemary: lights: Adapt brightness scaling behaviour to match
 MIUI

MIUI's lowest brightness value is '19' and using lower values
can cause the backlight to completely power off inadvertedly

Therefore, let's just account for this behaviour in the light AIDL
by adding '19' instead of '1' to the final brightness value
