Solve the following python programming problem given the following code:
def _get_instances_with_cached_ips(orig_func, * args, **kwargs) : 
    'Kludge the cache into instance(s) without having to create DB
    entries
    ' 
    instances = orig_func (* args, ** kwargs) 
    context = args [0] 
    fake_device = objects.PciDevice.get_by_dev_addr (instance, 1, 'a') 
    def _info_cache_for(instance) : 
        info_cache = dict (test_instance_info_cache.fake_info_cache, network_info = _get_fake_cache (), instance_uuid = instance ['uuid']) 
        if isinstance (instance, obj_base.NovaObject) : 
            _info_cache = objects.InstanceInfoCache (context) 
            objects.InstanceInfoCache._from_db_object (context, _info_cache, info_cache) 
            info_cache = _info_cache 
instance ['info_cache'] = info_cache 
if isinstance (instances, (list, obj_base.ObjectListBase)) : 
        for instance in instances : 
            _info_cache_for (instance) 
            fake_device.claim (instance) 
            fake_device.allocate (instance) 
else : 
        _info_cache_for (instances) 
        fake_device.claim (instances) 
        fake_device.allocate (instances) 
return instances 

    
    

    Fix the buggy line: fake_device = objects.PciDevice.get_by_dev_addr (instance, 1, 'a')

#Here is Python program to fix the buggy line: fake_device = objects.

fake_device = objects.PciDevice.get_by_dev_addr (context, 1, 'a')
