I think that description conflicts with what is implemented in this patch?
int gunyah_vm_add_resource_ticket(struct gunyah_vm *ghvm,
struct gunyah_vm_resource_ticket *ticket)
{
mutex_lock(&ghvm->resources_lock);
list_for_each_entry(iter, &ghvm->resource_tickets, vm_list) {
if (iter->resource_type == ticket->resource_type &&
iter->label == ticket->label) {
ret = -EEXIST;
goto out;
}
}

Where do we free memory pointed by 'resources' ptr?
