Subject: [PATCH 2/3] viafb: some small cleanup for global variables
We do not need viafb_second{,_virtual}_{xres,yres} outside of
viafbdev.c so move them there and eliminate the virtual ones where
the only sane usage is done during initalization.
Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@....de>
