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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: imx-hdmi: se corrige la pérdida de recuento de referencias en imx_hdmi_probe. La referencia que toma la instancia de_find_device_by_node() se debe liberar. Deberíamos usar put_device() para liberarla. Cuando falla devm_kzalloc(), no tiene un put_device(), lo que provocará una pérdida de recuento de referencias. Agregue el put_device() faltante para solucionar esto.
