From a487411a64816458bd4dbac91a1981ec31bb40d4 Mon Sep 17 00:00:00 2001 From: Leo Li Date: Thu, 23 Aug 2018 15:28:08 -0400 Subject: [PATCH] drm/amd/display: Use DRM helper for best_encoder [Why] Our implementation is functionally identical to DRM's Note that instead of checking if the provided id is 0, the helper follows through with the mode object search. However, It will still return NULL, since 0 is not a valid object id, and missed searches will return NULL. [How] Remove our implementation, and replace it with drm_atomic_helper_best_encoder.
