Subject: staging: comedi: ni_daq_700: change driver registration order
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f90398294753b3f88570af1c2a68032f6ae6bfbe;p=linux-beck.git

staging: comedi: ni_daq_700: 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.
