    Subject[PATCH 36/49] gma500: Rename the psb_intel_bios code
    Date
    From: Alan Cox <alan@linux.intel.com>

    This is generic for the PC class devices and also very similar to the i915
    intel_bios.c so rename it. That way the commonality will be obvious and we
    can look at merging them one day, or at least synching them up.
