From 5607ae85bd64208356567c77fed84a395d4e2182 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 14 Nov 2022 16:18:09 +0100 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.
