This variable is only used as a flag to indicate that the pci device has been enabled. Use the comedi_device 'iobase' variable to indicate this instead. This is how it's normally handled in the comedi pci drivers. Make the call to comedi_pci_disabled() in i_ADDI_Detach() common and move it to the end of the function. Both the if and else case require it.
