Subject: [PATCH AUTOSEL 5.10 030/100] drm/bridge/analogix/anx78xx: Setup encoder before registering connector
Date: Mon, 3 May 2021 12:37:19 -0400 [thread overview]
Message-ID: <20210503163829.2852775-30-sashal@kernel.org> (raw)
In-Reply-To: <20210503163829.2852775-1-sashal@kernel.org>
From: Lyude Paul <lyude@redhat.com>
[ Upstream commit 9962849d0871f5e53d0e3b3d84561f8f2847fbf4 ]
Since encoder mappings for connectors are exposed to userspace, we should
be attaching the encoder before exposing the connector to userspace. Just a
drive-by fix for an issue I noticed while fixing up usages of
drm_dp_aux_init()/drm_dp_aux_register() across the tree.
