Hi Jiri,

[auto build test ERROR on net-next/master -- if it's inappropriate base, please ignore]

config: i386-randconfig-x003-201540 (attached as .config)
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

All errors (new ones prefixed by >>):

   net/bridge/br_stp.c: In function 'br_set_state':
>> net/bridge/br_stp.c:49:8: error: implicit declaration of function 'switchdev_port_attr_set_deferred' [-Werror=implicit-function-declaration]
     err = switchdev_port_attr_set_deferred(p->dev, &attr);
           ^
   cc1: some warnings being treated as errors

    52					(unsigned int) p->port_no, p->dev->name);
