staging/xgifb: Replace XGI340_CR6B table with simple if/else
The XGI340_CR6B lookup table consists of the entries {0xaa, 0xaa, 0xaa, 0xaa} for an index <= 2 and {0x00, 0x00, 0x00, 0x00} for all other indices. The only user XGINew_SetDRAMDefaultRegister340 loops over these 4 values of a line with a for loop and since all entries are the same for each line we can simply replace the whole lookup table with a simple if/else assignment. Tested-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
