 * Name: aht10_register
 *
 * Description:
 *   Register the SHT2x character device as 'devpath'
 *
 * Input Parameters:
 *   devpath - The full path to the driver to register. E.g., "/dev/temp0"
 *   i2c     - An instance of the I2C interface to use to communicate with
 *             the AHT10
 *   addr    - The I2C address of the AHT10 (always 0x38).
 *
 * Returned Value:
 *   Zero (OK) on success; a negated errno value on failure.
