[PATCH 4.14 27/74] media: cec: CEC 2.0-only bcast messages were ignored

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Hans Verkuil <hverkuil-cisco@xs4all.nl>

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.
