From c3ee8c65f63799b02e1fb828bac99fd5008fb565 Mon Sep 17 00:00:00 2001 From: Bernard Zhao Date: Sat, 1 Aug 2020 20:02:13 +0800 Subject: drm/panel: remove return value of function drm_panel_add The function "int drm_panel_add(struct drm_panel *panel)" always returns 0, this return value is meaningless. Also, there is no need to check return value which calls "drm_panel_add and", error branch code will never run.
