DESCRIPTION

19       This routine is used to declare an I2C adapter when its bus number
20       doesn't matter or when its bus number is specified by an dt alias.
21       Examples of bases when the bus number doesn't matter: I2C adapters
22       dynamically added by USB links or PCI plugin cards.
23
24       When this returns zero, a new bus number was allocated and stored in
25       adap->nr, and the specified adapter became available for clients.
26       Otherwise, a negative errno value is returned.
