Use dev_err_probe() instead, which will demote these messages to debug level (thus removing the alarming messages from the console) when the error is -EPROBE_DEFER, and also has the advantage of including the error code if/when it happens to be something other than -EPROBE_DEFER. While here, add the missing \n to one of the format strings.
