Function atmel_hlcdc_attach_endpoint() defined in drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_output.c returns -ENODEV when function devm_kzalloc() fails. Codes related to this bug are shown as follows.

drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_output.c:
   34  static int atmel_hlcdc_attach_endpoint(struct drm_device *dev, int endpoint)
   35  {
...
   44  		return ret;
   45  
   46: 	encoder = devm_kzalloc(dev->dev, sizeof(*encoder), GFP_KERNEL);
   47  	if (!encoder)
   48  		return -EINVAL;	// should return -ENOMEM
