Re: problem installing cvs comedi

Thanks, it works fine.

Further I patched ni_mio_cs.c to compile with kernel 2.6.17. I have tested it 
with comedi_test and a simple AO -> AI loopback (in labview) and it seems to 
work.

Of couse you'll need to change the kbuild file since other pcmcia 
drivers still doesn't work.

Since dev_init_t no longer exist in 2.6.17 and pcmcia_device has no next 
member, a device list is no longer maintained. If cs_attach is called twice 
dev_list is writen over and the first call to cs_detact sets dev_list to 
NULL. I'm not sure if this is the right thing to do?

I'm not sure about all the corrections I have done, but I seems to work and I 
get no error messages from the kernel. I think the the dev_list should not be 
used at all anymore, but I couldn't find a good way of avoiding it.

I hope it is usefull, and please let me know it I should do some specific 
testing or if you have other comments.

Regards
Torben
