You missed adding the mana_ prefix here. There might be others.

+#define CQE_POLLING_BUFFER 512
+struct ana_eq {
+	struct gdma_queue *eq;
+	struct gdma_comp cqe_poll[CQE_POLLING_BUFFER];
+};

+static int ana_poll(struct napi_struct *napi, int budget)
+{

You also have a few cases of ana_, not mana_. There might be others.
