Another drive-by fix I found when fixing DP AUX adapter across the kernel
tree - make sure we don't leak resources (and by proxy-AUX adapters) on
failures in anx6345_bridge_attach() by unrolling on errors.

Just another drive-by fix I noticed while going through the tree to cleanup
DP aux adapter registration - make sure we unregister the DP AUX dev if

Since AUX adapters on nouveau have their respective DRM connectors as
parents, we need to make sure that we register then after their connectors.

Another case of linking an encoder to a connector after the connector's
been registered. The proper place to do this is before connector
registration, so let's fix that.

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.

Surprisingly, this bridge actually registers it's AUX adapter at the
correct time already. Nice job! However, it does forget to actually
unregister the AUX adapter, so let's add a bridge function to handle that.

tform device instead of being a grandchild of the DRM device.
Since we're about to add a backpointer to a DP AUX channel's respective DRM
device, let's fix this so that we don't potentially allow userspace to use
the AUX channel before we've associated it with it's DRM co
. Instead,
call drm_dp_aux_init() in tc_probe() and wait until tc_bridge_attach() to
register our AUX channel. We also add tc_bridge_detach() to handle
unregistering the AUX adapter once the bridge has been disconnected.

correctly anyway, let's move platforms using PCH_ICP which aren't handled
