Yep.
To clarify what Jonathan said (see line below with plus + ) :

static struct spi_driver ad9832_driver = {
        .driver = {
                .name   = "ad9832",
+              .of_match_table = ad9832_of_match,
        },
        .probe          = ad9832_probe,
        .remove         = ad9832_remove,
        .id_table       = ad9832_id,
};
