Subjectsmall bug? in drivers/video/vgacon.c
Hi.

Function drivers/video/vgacon.c:vgacon_scrolldelta() doesn't work
when get 1 or -1 as 2nd arg (it doesn't scroll).
This bug can be seen rarely, cos usually this func never called with 1 or -1.
I don't quite understand, how this func works :-) but vgacon_scrolldelta
works properly with this small patch.
