Subject: [PATCH] drm/i2c: tda998x: don't register the connector
Date: Mon, 25 Jul 2016 11:55:48 +0100	[thread overview]
Message-ID: <1469444148-19003-1-git-send-email-brian.starkey@arm.com> (raw)

The connector shouldn't be registered until the rest of the whole device
is set up, so that consistent state is presented to userspace.

As drm_dev_register() now registers all of the connectors anyway,
there's no need to explicitly do it in individual drivers so remove
the calls to drm_connector_register()/drm_connector_unregister().

This allows componentised drivers to use tda998x without having racy
initialisation.
