Description
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.
