    [media] samples: v4l: from Documentation to samples directory · 0185f850

    With the new autoksyms support, we can run into a situation where
    the v4l pci skeleton module is the only one using some exported
    symbols that get dropped because they are never referenced by
    the kernel otherwise, causing a build problem:
    
    ERROR: "vb2_dma_contig_memops" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
    ERROR: "vb2_dma_contig_init_ctx_attrs" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
    ERROR: "v4l2_match_dv_timings" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
    ERROR: "v4l2_find_dv_timings_cap" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
    ERROR: "v4l2_valid_dv_timings" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
    ERROR: "v4l2_enum_dv_timings_cap" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
    ERROR: "vb2_dma_contig_cleanup_ctx" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
    
    Specifically, we do look in the samples directory for users of
    symbols, but not the Documentation directory.
    
    This solves the build problem by moving the connector sample into
    the same directory as the other samples.
