X-Git-Tag: next-20111128~7^2~15
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0ebf538b8ad274c621869b5008779b36c684609a;p=karo-tx-linux.git

staging: xgifb: vb_setmode: make XGI_XG21BLSignalVDD() static

XGI_XG21BLSignalVDD() can be made static. Move the function, so that
forward declaration is not needed.
