Subject: [PATCH 5.10 121/238] drm/rockchip: lvds: do not print scary message when probing defer

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

[ Upstream commit 52d11c863ac92e36a0365249f7f6d27ac48c78bc ]

This scary message can misled the user into thinking something bad has
happened and needs to be fixed, however it could simply be part of a
normal boot process where EPROBE_DEFER is taken into account. Therefore,
let's use dev_err_probe so that this message doesn't get shown (by
default) when the return code is EPROBE_DEFER.
