I agree that using dev_err_probe() outside of a probe path is
inappropriate. And I agree that your patch addresses that problem
in the context of changes made by the cited commit.
But, based on my reading of dev_err_probe(), I think the text above is
slightly misleading. This is because deferred status is only set in the
case where the err passed to dev_err_probe() is -EPROBE_DEFER. And I do
suspect that is never the case for the calls removed by this patch.
