[PATCH 66/90] staging: comedi: dt3000: move the setup_pci() code into the attach

From: H Hartley Sweeten
Date: Wed Jul 18 2012 - 21:58:07 EST


The setup_pci() function simply calls comedi_pci_enable() to enable
the device then ioremaps the pci address. Move the code directly
into the attach function as is more typical for the comedi pci
drivers.
