[PATCH/RFC] atafb line length

[Geert Uytterhoeven <geert@linux-m68k.org>]

Make sure fix->line_length is always set, as some applications need it because
they don't have fallback code if line_length is zero.

Works on ARAnyM (Falcon emulation), but par->next_line is not set on any other
Atari variant?

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
