Subject: [PATCH] livedisplay: Fix endless loop for devices that don't support
 outdoor mode.

There was a logic mistake that caused _all_ modes to be skipped if
outdoor mode isn't supported. In order to avoid such mistakes in the
future, also simplify the logic and make it more easily understandable.
