 * Name: adt7320_register
 *
 * Description:
 *   Register the ADT7320 character device as 'devpath'
 *
 * Input Parameters:
 *   devpath - The full path to the driver to register. E.g., "/dev/temp0"
 *   spi     - An instance of the SPI interface to use to communicate with
 *   spidev - Number of the spi device (used to determine what chip
 *            should be selected).
 *
 * Returned Value:
 *   Zero (OK) on success; a negated errno value on failure.
