From d106de1b9e3670abffb2a4e18dbc88170c30b452 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 4 Dec 2019 08:52:08 +0100 Subject: [PATCH] media: cec: CEC 2.0-only bcast messages were ignored commit cec935ce69fc386f13959578deb40963ebbb85c3 upstream. Some messages are allowed to be a broadcast message in CEC 2.0 only, and should be ignored by CEC 1.4 devices. Unfortunately, the check was wrong, causing such messages to be marked as invalid under CEC 2.0.
