Subject: staging/xgifb: Simplify XGISetModeNew
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e44adfdb6740f5673612a3060b8d3120ccafd5d1;p=linux-beck.git

staging/xgifb: Simplify XGISetModeNew

This patch simplifies the code of XGISetModeNew by reordering the
if/else if/case conditions when both branches are doing exactly the
same.
