Update all changes (already those not included in linux-next) which are in
the queue for 2.6.33 for all comedi PCMCIA drivers. Compile-tested only, and
I'll queue it up with the other PCMCIA patches.

Subject: [PATCH 1/1] pcmcia/staging: update comedi drivers

Update comedi PCMCIA drivers to work with recent PCMCIA changes documented
in Documentation/pcmcia/driver-changes.txt:

- use pcmcia_config_loop()
- don't use PCMCIA_DEBUG, but use dev_dbg()
- don't use cs_error()
- re-use prod_id and card_id values already stored
