Avoid spamming the log. The backlight controller on DCN chips
gets powered down when the display is off, so if you attempt to
set the backlight level when the display is off, you'll get this
message. This isn't a problem as we cache the requested backlight
level if it's adjusted when the display is off and set it again
during modeset.
