Subject: [PATCH v2] component: Silence bind error on -EPROBE_DEFER
Date: Sat, 11 Apr 2020 13:02:41 -0600	[thread overview]
Message-ID: <20200411190241.89404-1-james.hilliard1@gmail.com> (raw)

If a component fails to bind due to -EPROBE_DEFER we should not log an
error as this is not a real failure.

Fixes:
vc4-drm soc:gpu: failed to bind 3f902000.hdmi (ops vc4_hdmi_ops): -517
vc4-drm soc:gpu: master bind failed: -517
