drm/rockchip: lvds: do not overwrite error code
[ 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.
