int i2o_driver_dispatch	(	struct i2o_controller *	c,
		u32	m
	)

i2o_driver_dispatch - dispatch an I2O reply message : I2O controller of the message : I2O message number

The reply is delivered to the driver from which the original message was. This function is only called from interrupt context.

Returns 0 on success and the message should not be flushed. Returns > 0 on success and if the message should be flushed afterwords. Returns negative error code on failure (the message will be flushed too).

void

)

i2o_driver_init - initialize I2O drivers (OSMs)

Registers the I2O bus and allocate memory for the array of OSMs.

Returns 0 on success or negative error code on failure.
