> The function kobject_init_and_add alloc memory like:
> kobject_init_and_add->kobject_add_varg->kobject_set_name_vargs
> ->kvasprintf_const->kstrdup_const->kstrdup->kmalloc_track_caller
> ->kmalloc_slab, in err branch this memory not free. If use
> kmemleak, this path maybe catched.
> These changes are to add kobject_put in kobject_init_and_add
> failed branch, fix potential memleak.
> Changes since V2:
> *remove duplicate kobject_put in kfd_procfs_init.
