generic_driver_init()

int generic_driver_init	(	const char *	name,
		void *	object
	)

This is a generic initialization function that performs initialization of driver corresponding to the driver name.

Parameters

[in]	name	driver's name.
[in]	object	The object which wants to initialize. Usually, global_config in this place.

Returns

0 for success to init, other value for fail to init.

Parameters

[in]

name

The name of driver.

Returns

index number which related to name
