From 071a69cde19634823b59bd231f483c3e8e8e76bb Mon Sep 17 00:00:00 2001 From: Matheus Castello Date: Wed, 22 Mar 2023 15:38:21 +0100 Subject: [PATCH] drm/bridge: lt8912b: return EPROBE_DEFER if bridge is not found commit 1a70ca89d59c7c8af006d29b965a95ede0abb0da upstream. Returns EPROBE_DEFER when of_drm_find_bridge() fails, this is consistent with what all the other DRM bridge drivers are doing and this is required since the bridge might not be there when the driver is probed and this should not be a fatal failure.
