[PATCH v5 9/9] drm: exynos: exynos_hdmi: use cec_notifier_conn_(un)register

2019-08-07 Thread Dariusz Marcinkiewicz
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 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.
