RE: [PATCH] sound: fsl: add missing put_device() call in imx_hdmi_probe()

quoted

From: Wang Qing <redacted>

of_find_device_by_node() takes a reference to the embedded struct device 
which needs to be dropped when error return.

...

quoted

       data = devm_kzalloc(&pdev->dev, sizeof(*data), GFP_KERNEL);
       if (!data) {
+             put_device(&cpu_pdev->dev);

If it's of_find_device_by_node() you need an of_node_put() since you're
dropping a reference on the OF node.

Label fail will drop a reference on the OF node.
Also, put_device() is called later except this branch, 
we just need to add put_device() here.

Thanks,
Qing
