Subject: [PATCH v3 04/20] drm/bridge/cdns-mhdp8546: Register DP aux channel with userspace
Date: Mon, 19 Apr 2021 18:55:06 -0400 [thread overview]
Message-ID: <20210419225523.184856-5-lyude@redhat.com> (raw)
In-Reply-To: <20210419225523.184856-1-lyude@redhat.com>
Just adds some missing calls to
drm_dp_aux_register()/drm_dp_aux_unregister() for when we attach/detach the
bridge.
