commit: 3991c5c80beaf7eb9bce61e0b2f8f449e351a38e [3/33] i2c: Switch to using gpiod interface for gpio bus recovery
config: ia64-generic_defconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 6.2.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 3991c5c80beaf7eb9bce61e0b2f8f449e351a38e
        # save the attached .config to linux build tree

Note: the wsa/renesas/topic/rcar-i2c-recovery HEAD 3b8d1dbaefe52dfbecef1713d028e446c367d184 builds fine.
      It only hurts bisectibility.
