Hi Christoph,

(I don't think the patches of this series ever hit the ISDN related addresses
still found in MAINTAINERS. And now I might be a bit late.)

Is this intentional? You didn't touch the procinfo method in the other ISDN
drivers, as far as I can see.

(If it was intentional, gigaset_procinfo() can of course be removed.)
