Subject: staging/xgifb: Remove unused values in XG27_SR13 and XGI340_SR13
X-Git-Tag: upstream/snapshot3+hdmi~5696^2~114
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=86c6c948dabff1ff84213e5fb50684ad32895f25;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

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.
