Subject: [PATCH 4.19 073/148] drm/rockchip: lvds: do not overwrite error code

From: Quentin Schulz <quentin.schulz@...obroma-systems.com>

[ Upstream commit 79b09453c4e369ca81cfb670d0136d089e3b92f0 ]

ret variable stores the return value of drm_of_find_panel_or_bridge
which can return error codes different from EPROBE_DEFER. Therefore,
let's just return that error code instead of forcing it to EPROBE_DEFER.
