staging/xgifb: Remove unused values in XGI340_cr41 and XGI27_cr41
In the lookup tables XGI340_cr41 and XGI27_cr41 only the first three values are used of each 'line', thus the remaining fields can be removed. Rationale: - vb_init.c uses pVBInfo->ram_type for the 'column' index for pVBInfo->CR40. - pVBInfo->ram_type is assigned the return value of XGINew_GetXG20DRAMType which can only be 0, 1 or 2 - pVBInfo->CR40 is assigned to either XGI340_cr41 or XGI27_cr41 in vb_setmode.c -> only the first three values are used. This becomes also evident as values 3-7 are all 0. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
