In the Linux kernel, the following vulnerability has been resolved:

ASoC: imx-hdmi: Fix refcount leak in imx_hdmi_probe

of_find_device_by_node() takes reference, we should use put_device()
to release it. when devm_kzalloc() fails, it doesn't have a
put_device(), it will cause refcount leak.
Add missing put_device() to fix this.
