/**
 * dev_get_regmap(): Obtain the regmap (if any) for a device
 *
 * @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.
