staging: comedi: adl_pci6208: remove pci6208_pci_setup()
Browse files Browse the repository at this point in the history
Refactor pci6208_pci_setup() into the attach function. This
function simply enables the pci device and gets the PCI iobase
address used by the driver. There's no need for a separate
function to handle this.
