Very close, but you missed this bit:

--- a/drivers/net/ethernet/sfc/mcdi_mon.c
+++ b/drivers/net/ethernet/sfc/mcdi_mon.c
@@ -142,7 +142,7 @@ static int efx_mcdi_mon_update(struct efx_nic *efx)
 static int efx_mcdi_mon_get_entry(struct device *dev, unsigned int index,
 				  efx_dword_t *entry)

-	struct efx_nic *efx = dev_get_drvdata(dev);
+	struct efx_nic *efx = dev_get_drvdata(dev->parent);
 	struct efx_mcdi_mon *hwmon = efx_mcdi_mon(efx);
 	int rc;

With that addition, it works for me, and you can add my Reviewed-by.
