How about just returning ret like below?
if (IS_ERR(dp->phy)) {
dev_err(dp->dev, "no DP phy configured\n");
return PTR_ERR(ret);
}
And then you can handle the error at probe function properly.

Can anyone give me tested-by after test? I cannot test this module
because I have no any board equipped with dp panel.
Jingoo or other?

Is someone taking care of this patch ? We already have got the corresponsding
dp-phy patch merged, so we should also get this patch in.

[PATCH 2/3] drm/exynos: dp: Remove support for unused dptx-phy
Now that we have moved to generic phy based bindings,
we don't need to have any code related to older dptx-phy.
Nobody is using this dptx-phy anymore, so removing the
same.
