Description

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: fix potential memleak in 'add_widget_node' As 'kobject_add' may allocated memory for 'kobject->name' when return error. And in this function, if call 'kobject_add' failed didn't free kobject. So call 'kobject_put' to recycling resources.
