yes, that was my first impression.  The _names_ of those variables is a
real problem.  lcd_mode, DeviceStatus, second_size, primary_dev, etc.  The
driver is attempting to reserve all those names for itself, kernel-wide.

So at a minimum, going through and prepending viafb_ onto all those would
be needed.


There are a number of layout glitches in there.  Such as a strange combination of
two styles:

void foo(void)
{

versus

void foo(void ) {

Many of these things can be pinpointed by processing the diff with
scripts/checkpatch.pl.


Administrative note: all nine patches had the same title "viafb: VIA Frame
Buffer Device Driver".  Please choose unique and meaningful names for each
patch, such as "viafb: add utility header file".


Apart from those fairly easily-fixed things, the driver looks pretty good
from a quick scan, given how large it is, and given that it probably has
been around for quite a long time..
