max17616_iio_init()

int max17616_iio_init	(	struct max17616_iio_desc **	iio_desc,
		struct max17616_iio_desc_init_param *	init_param )

Initializes the MAX17616 IIO descriptor.

Parameters

iio_desc	- Pointer to IIO device descriptor.
init_param	- Device initialization parameters.

Returns

0 in case of success, an error code otherwise.
