Subject: staging: comedi: cb_das13_cs: change driver registration order
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=64c205f99790798fdcf42ea5093df1393a867e30;p=deliverable%2Flinux.git

staging: comedi: cb_das13_cs: change driver registration order

As done with the other comedi driver types, register the
comedi_driver first then the pcmcia_driver. Also, make
sure the pcmcia_driver registration succeeds and unregister
the comedi_driver it it fails.
