NAME
       i2c_add_numbered_adapter - declare i2c adapter, use static bus number

SYNOPSIS
       int i2c_add_numbered_adapter(struct i2c_adapter * adap);

ARGUMENTS
       adap
	   the adapter to register (with adap->nr initialized)

CONTEXT
       can sleep

DESCRIPTION
       This routine is used to declare an I2C adapter when its bus number
       matters. For example, use it for I2C adapters from system-on-chip CPUs,
       or otherwise built in to the system´s mainboard, and where
       i2c_board_info is used to properly configure I2C devices.

       If no devices have pre-been declared for this bus, then be sure to
       register the adapter before any dynamically allocated ones. Otherwise
       the required bus ID may not be available.

       When this returns zero, the specified adapter became available for
       clients using the bus number provided in adap->nr. Also, the table of
       I2C devices pre-declared using i2c_register_board_info is scanned, and
       the appropriate driver model device nodes are created. Otherwise, a
       negative errno value is returned.
