From 86c6c948dabff1ff84213e5fb50684ad32895f25 Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Tue, 5 Feb 2013 22:32:30 +0100 Subject: staging/xgifb: Remove unused values in XG27_SR13 and XGI340_SR13 In the lookup tables XG27_SR13 and XGI340_SR13 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->SR15. - pVBInfo->ram_type is assigned the return value of XGINew_GetXG20DRAMType which can only be 0, 1 or 2 - pVBInfo->SR15 is assigned to either XG27_SR13 or XGI340_SR13 in vb_setmode.c -> only the first three values are used. This becomes also evident as values 3-7 are all 0.
