Also it seems like you missed this one:

/* A Structure for boards to register fixups with the PHY Lib */
struct phy_fixup {
        struct list_head list;
        char bus_id[20];
	^================
        u32 phy_uid;
        u32 phy_uid_mask;
        int (*run)(struct phy_device *phydev);
};

Did you really run into naming conflicts where increasing the bus ID
size became the only solution here?
