Subject: [media] cec: update log_addr[] before finishing configuration
From: Hans Verkuil <hansverk@xxxxxxxxx>
[ Upstream commit 7af26f889eb67db272021a939f7d4a57e96dd961 ]
The loop that sets the unused logical addresses to INVALID should be
done before 'configured' is set to true. This ensures that cec_log_addrs
is consistent before it will be used.
