Subject: [PATCH] drm/vc4: crtc: Make encoder lookup helper public
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We'll need a function that looks up an encoder by its vc4_encoder_type.
Such a function is already present in the CRTC code, so let's make it
public so that we can reuse it in the unit tests.
