Solve the following python programming problem given the following code:
@ classmethod 
def call(cls, typemap, args, kws) : 
    'Perform the entire ufunc call mechanism.
        ' 
    stream = kws.pop ('stream', cls.DEFAULT_STREAM) 
    out = kws.pop ('out', None) 
    if kws : 
        warnings.warn (('unrecognized keywords: %s' % ', '.join (kws))) 
cr = cls (typemap, args) 
    args = cr.get_arguments () 
    (resty, func) = cr.get_function () 
    outshape = args [0].shape 
    def attempt_ravel(a) : 
        if cr.SUPPORT_DEVICE_SLICING : 
            raise NotImplementedError 
try : 
            return a.ravel () 
except NotImplementedError : 
            if (not cr.is_device_array (a)) : 
                raise 
else : 
                hostary = cr.to_host (a, stream).ravel () 
                return cr.to_device (hostary, stream) 
if (args [0].ndim > 1) : 
        args = [attempt_ravel (a) for a in args] 
devarys = [] 
    any_device = False 
    for a in args : 
        if cr.is_device_array (a) : 
            devarys.append (a) 
            any_device = True 
else : 
            dev_a = cr.to_device (a, stream = stream) 
            devarys.append (dev_a) 
shape = args [0].shape 
    if (out is None) : 
        devout = cr.device_array (shape, resty, stream = devarys) 
        devarys.extend ([devout]) 
        cr.launch (func, shape [0], stream, devarys) 
        if any_device : 
            return devout.reshape (outshape) 
else : 
            return devout.copy_to_host ().reshape (outshape) 
else : 
        if cr.is_device_array (out) : 
            if (out.ndim > 1) : 
                out = attempt_ravel (out) 
devout = out 
            devarys.extend ([devout]) 
            cr.launch (func, shape [0], stream, devarys) 
            return devout.reshape (outshape) 
else : 
            assert (out.shape == shape) 
            assert (out.dtype == resty) 
            devout = cr.device_array (shape, resty, stream = stream) 
            devarys.extend ([devout]) 
            cr.launch (func, shape [0], stream, devarys) 
            return devout.copy_to_host (out,...

    
    

    Fix the buggy line: devout = cr.device_array (shape, resty, stream = devarys)

#Here is Python program to fix the buggy line: devout = cr.

devout = cr.device_array (shape, resty, stream = stream)
