From 42cbe11cddd9cf9d039c5fb5730359fcbb2543a8 Mon Sep 17 00:00:00 2001 From: Matheus Castello Date: Wed, 22 Mar 2023 15:38:21 +0100 Subject: drm/bridge: lt8912b: return EPROBE_DEFER if bridge is not found 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.
