Subject: [Nouveau] [PATCH 07/30] drm/bridge/analogix/anx78xx: Add missing drm_dp_aux_unregister() call
Date: Fri, 19 Feb 2021 16:53:03 -0500
Message-ID: <20210219215326.2227596-8-lyude@redhat.com> (raw)
In-Reply-To: <20210219215326.2227596-1-lyude@redhat.com>

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.
