 * Description:
 *   Register the MS58XX character device as 'devpath'.
 *
 * Input Parameters:
 *   devpath - The full path to the driver to register, e.g., "/dev/press0".
 *   i2c     - An I2C driver instance.
 *   addr    - The I2C address of the MS58XX.
 *   osr     - The oversampling ratio.
 *   model   - The MS58XX model.
 *
 * Returned Value:
 *   Zero (OK) on success; a negated errno value on failure.
