Re: [Patch 2.3.40] Sedlbauer PnP-Card SpeedWin

Hi,

ok, I've done a bit of cleanup work. I think this change could go into
the kernel. If someone has the Card-Identities for the Sedlbauer
SpeedFax+ and the Seldbauer SpeedWin2, I would be glad if someone let me
know.

At least this patch works fine for me. It is against kerbel 2.3.40.

Bye
Martin
