Subject: [PATCH v2] drm/nouveau: dispnv50: Remove nv50_mstc_best_encoder()
Date:   Fri, 13 Sep 2019 18:37:20 -0400
Message-Id: <20190913223721.10185-1-lyude@redhat.com>

Precedence: bulk

When drm_connector_helper_funcs->atomic_best_encoder is defined,
->best_encoder is ignored by the atomic modesetting helpers. That being
said, this hook is completely broken anyway - it always returns the
first msto for a given mstc, despite the fact it might already be in
use.

So, just get rid of it. We'll need this in a moment anyway, when we make
mstos per-head as opposed to per-connector.

Changes since v1:
* Fix typo in documentation - imirkin
