From: Dariusz Marcinkiewicz <darekm@xxxxxxxxxx> [ Upstream commit 71137bfd98973efb7b762ba168df077b87b34311 ] Use the new cec_notifier_conn_(un)register() functions to (un)register the notifier for the HDMI connector, and fill in the cec_connector_info. Changes since v7: - err_runtime_disable -> err_rpm_disable Changes since v2: - removed unnecessary call to invalidate phys address before deregistering the notifier, - use cec_notifier_phys_addr_invalidate instead of setting invalid address on a notifier.
