  *
  * @dev: Device to retrieve the map for
  * @name: Optional name for the register map, usually NULL.
  *
  * Returns the regmap for the device if one is present, or NULL.  If
  * name is specified then it must match the name specified when
  * registering the device, if it is NULL then the first regmap found
  * will be used.  Devices with multiple register maps are very rare,
  * generic code should normally not need to specify a name.
