This helper should help with the migration of existing drivers to use the new i2c_driver .probe_new callback, which does not provide the device id with the pointer to the driver data as the previous .probe callback. As part of the patchset, migrated the bmp280 IIO driver to .new_probe callback using the new helper. Changes from v1 --> v2: * Add further clarification that the device queried needs to be bound to the driver. * Drops extra newline after function return. * Discard unrelated style changes.
