Subject: [PATCH v7 0/9] drm: cec: convert DRM drivers to the new notifier API

This series updates DRM drivers to use new CEC notifier API.

Changes since v6:
	Made CEC notifiers' registration and de-registration symmetric
	in tda998x and dw-hdmi drivers. Also, accidentally dropped one
	patch in v6 (change to drm_dp_cec), brought it back now.
Changes since v5:
        Fixed a warning about a missing comment for a new member of
	drm_dp_aux_cec struct. Sending to a wider audience,
	including maintainers of respective drivers.
Changes since v4:
	Addressing review comments.
Changes since v3:
        Updated adapter flags in dw-hdmi-cec.
Changes since v2:
	Include all DRM patches from "cec: improve notifier support,
	add connector info connector info" series.
Changes since v1:
	Those patches delay creation of notifiers until respective
	connectors are constructed. It seems that those patches, for a
	couple of drivers, by adding the delay, introduce a race between
	notifiers' creation and the IRQs handling threads - at least I
	don't see anything obvious in there that would explicitly forbid
	such races to occur. v2 adds a write barrier to make sure IRQ
	threads see the notifier once it is created (replacing the
	WRITE_ONCE I put in v1). The best thing to do here, I believe,
	would be not to have any synchronization and make sure that an IRQ
	only gets enabled after the notifier is created.
Dariusz Marcinkiewicz (9):
  drm_dp_cec: add connector info support.
  drm/i915/intel_hdmi: use cec_notifier_conn_(un)register
  dw-hdmi-cec: use cec_notifier_cec_adap_(un)register
  tda9950: use cec_notifier_cec_adap_(un)register
  drm: tda998x: use cec_notifier_conn_(un)register
  drm: sti: use cec_notifier_conn_(un)register
  drm: tegra: use cec_notifier_conn_(un)register
  drm: dw-hdmi: use cec_notifier_conn_(un)register
  drm: exynos: exynos_hdmi: use cec_notifier_conn_(un)register
