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 Signed-off-by: James Hilliard <james.hilliard1@xxxxxxxxx> Link: https://lore.kernel.org/r/20200411190241.89404-1-james.hilliard1@xxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/base/component.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/drivers/base/component.c b/drivers/base/component.c index 08da6160e94d..55f0856bd9b5 100644 --- a/drivers/base/component.c +++ b/drivers/base/component.c @@ -162,7 +162,8 @@ static int try_to_bring_up_master(struct master *master, ret = master->ops->bind(master->dev); if (ret < 0) { devres_release_group(master->dev, NULL); - dev_info(master->dev, "master bind failed: %d\n", ret); + if (ret != -EPROBE_DEFER) + dev_info(master->dev, "master bind failed: %d\n", ret); return ret; } @@ -431,8 +432,9 @@ static int component_bind(struct component *component, struct master *master, devres_release_group(component->dev, NULL); devres_release_group(master->dev, NULL); - dev_err(master->dev, "failed to bind %s (ops %ps): %d\n", - dev_name(component->dev), component->ops, ret); + if (ret != -EPROBE_DEFER) + dev_err(master->dev, "failed to bind %s (ops %ps): %d\n", + dev_name(component->dev), component->ops, ret); } return ret; -- 2.25.1
