+Subject: [PATCH] net: phy: export fixed_phy_register()
+
+When building the bcmgenet driver as module, I get:
+
+ERROR: "fixed_phy_register" [drivers/net/ethernet/broadcom/genet/genet.ko] undefined!
+
+commit b0ba512e225d72 ("net: bcmgenet: enable driver to work without device
+tree") which added a call to fixed_phy_register. But fixed_phy_register
+needs to be exported if used from a module.
