drivers: media: platform/meson: does there exist a refcount error in function meson_ao_cec_probe

[易林 <yilin@xxxxxxxxx>]

Hi，all:
when reviewing code of function meson_ao_cec_probe:
In Linux kernel version before v5.4, function meson_ao_cec_probe hold a notify  reference by cec_notifier_get, when err happens, it will release notify 
twice by cec_notifier_put, does here exist a redundant put in error handling of cec_register_adapter return value?
    static int meson_ao_cec_probe(struct platform_device *pdev)
{
        ao_cec->notify = cec_notifier_get(hdmi_dev);
	if (!ao_cec->notify)
		return -ENOMEM;
	if (ret) {
		dev_err(&pdev->dev, "core clock set rate failed\n");
		goto out_probe_clk;
	}

	device_reset_optional(&pdev->dev);

	ao_cec->pdev = pdev;
	platform_set_drvdata(pdev, ao_cec);

	ret = cec_register_adapter(ao_cec->adap, &pdev->dev);
	if (ret < 0) {
		cec_notifier_put(ao_cec->notify); // a redundant put here ?
		goto out_probe_clk;
	}
	...
out_probe_clk:
	clk_disable_unprepare(ao_cec->core);

out_probe_adapter:
	cec_delete_adapter(ao_cec->adap);

out_probe_notify:
	cec_notifier_put(ao_cec->notify);

	dev_err(&pdev->dev, "CEC controller registration failed\n");

	return ret;
}
