[PATCH AUTOSEL 4.19 14/31] component: Silence bind error on -EPROBE_DEFER
From: Sasha Levin
Date: Thu May 14 2020 - 15:04:24 EST
From: James Hilliard <james.hilliard1@xxxxxxxxx>
[ Upstream commit 7706b0a76a9697021e2bf395f3f065c18f51043d ]
If a component fails to bind due to -EPROBE_DEFER we should not log an
error as this is not a real failure.
Fixes messages like:
vc4-drm soc:gpu: failed to bind 3f902000.hdmi (ops vc4_hdmi_ops): -517
vc4-drm soc:gpu: master bind failed: -517
