## Description

In the Linux kernel, the following vulnerability has been resolved: remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev() The kfree() should be called when of_irq_get_byname() fails or devm_request_threaded_irq() fails in qcom_add_sysmon_subdev(), otherwise there will be a memory leak, so add kfree() to fix it.
