Hi all,
Has anyone else run into a problem compiling the Cyclades serial board
driver under 2.5.x when you have ISA defined as well? I've done a
quick hack patch to make it compile. I've been running 2.4.21-rc*
lately, so it's time I started to actually test this patch below and
see how it works.
I read the file Documentation cli-sti-removal.txt and I think I've
done the right things here.
