    drm/fb: fix FBIOGET/PUT_VSCREENINFO pixel clock handling

    When the framebuffer driver does not publish detailed timing information
    for the current video mode, the correct value for the pixclock field is
    zero, not -1.

    Since pixclock is actually unsigned, the value -1 would be interpreted
    as 4294967295 picoseconds (i.e., about 4 milliseconds) by
    register_framebuffer() and userspace programs.

    This patch allows X.org's fbdev driver to work.
