4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Hans Verkuil <[email protected]> [ 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.
