    drm/openchrome: Not increment horizontal display fetch count by 1
    
    This does not appear to affect newer devices, but it causes KM400(A)
    chipset family's FP to display a slanted picture. The problem was
    observed on Averatec 3250HX laptop likely with KN400(A) chipset (not
    sure it is KN400 or KN400A).
