This function is not introduced in this patch, but I'm commenting here.
Looks like it only operates on an OF node, so how about naming it
of_get_nand_ecc_config().

+{
+	struct device_node *dn = nanddev_get_of_node(nand);
+	int strength, size;
+
+	nand->ecc.user_conf.engine_type = of_get_nand_ecc_engine_type(dn);
+	nand->ecc.user_conf.algo = of_get_nand_ecc_algo(dn);
+	nand->ecc.user_conf.placement = of_get_nand_ecc_placement(dn);
+
+	strength = of_get_nand_ecc_strength(dn);
+	if (strength >= 0)
+		nand->ecc.user_conf.strength = strength;
+
+	size = of_get_nand_ecc_step_size(dn);
+	if (size >= 0)
+		nand->ecc.user_conf.step_size = size;
+
+	if (of_get_nand_ecc_maximize(dn))
+		nand->ecc.user_conf.flags |= NAND_ECC_MAXIMIZE;
+}
+EXPORT_SYMBOL(nand_ecc_read_user_conf);
