From f90398294753b3f88570af1c2a68032f6ae6bfbe Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 22 Jun 2012 16:15:16 -0700 Subject: [PATCH] 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.
