[1/1] remoteproc: sysmon: fix memory leak in qcom_add_sysmon_subdev() commit: e01ce676aaef3b13d02343d7e70f9637d93a3367 Best regards,

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.
