commit: cce767df8b5328262c87e23ca7a5d74c17bcdad0 [5/14] media: platform: pxa_camera: convert to vb2

        chmod +x ~/bin/make.cross
        git checkout cce767df8b5328262c87e23ca7a5d74c17bcdad0
        # save the attached .config to linux build tree
        make.cross ARCH=arm 

Note: the rjarzmik/work/v4l2 HEAD 1646e167bd7bc014ad5c385e6a3be70d6670bbf9 builds fine.
      It only hurts bisectibility.
