Subject: [PATCH] dt-bindings: leds: leds-bcm63138: unify full stops in
descriptions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Description of "reg" doesn't have full stop at the end. It makes sense
as it's a one-sentence only. Use the same style for "active-low".
