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.
