This is part of an ongoing transition to single-argument i2c probe functions. Old-style probe functions involve a call to i2c_match_id: in drivers/i2c/i2c-core-base.c, /* * When there are no more users of probe(), * rename probe_new to probe. */ if (driver->probe_new) status =3D driver->probe_new(client); else if (driver->probe) status =3D driver->probe(client, i2c_match_id(driver->id_table, clie= nt)); else status =3D -EINVAL; Drivers which don't need the second parameter can be declared using probe_new instead, avoiding the call to i2c_match_id. Drivers which do can still be converted to probe_new-style, calling i2c_match_id themselves (as is done currently for of_match_id).
