commit: bcf4420283d1338b39773be8b487563c90986959 [64/67] usb: gadget: move gadget API functions to udc-core
config: arm-mvebu_v7_defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 5.3.1-8) 5.3.1 20160205
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout bcf4420283d1338b39773be8b487563c90986959
        # save the attached .config to linux build tree
        make.cross ARCH=arm 

Note: the balbi-usb/testing/next HEAD 327475d7f63aa161bdc3bf7f9d693d9aafcd4518 builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
