commit: a16ca26d3fef14bc9559d422ce8c546a3d18214d [10/12] gpio: handle compatible ioctl() pointers
config: x86_64-rhel (attached as .config)
compiler: gcc-4.9 (Debian 4.9.3-14) 4.9.3
reproduce:
        git checkout a16ca26d3fef14bc9559d422ce8c546a3d18214d
        # save the attached .config to linux build tree
        make ARCH=x86_64 

Note: the gpio/chardev-step-2 HEAD bbd57b1dbd892e0855fa4e9d929e48ef79fb13f6 builds fine.
      It only hurts bisectibility.
